An absorbent article comprising: an absorbent member; and a topsheet disposed on a skin-facing surface side of the absorbent member, the absorbent article having a longitudinal direction, which corresponds to a front-rear direction of a wearer, and a lateral direction orthogonal to the longitudinal direction, wherein the topsheet comprises a layered body formed of a first sheet, disposed on the skin-facing surface side, and a second sheet, disposed on a non-skin-facing surface side, the first sheet and the second sheet of the layered body are partially joined to form a plurality of joined regions, and the first sheet forms a plurality of projections, which protrude from the second sheet toward a wearer’s skin side, at a portion other than the joined regions, the projections comprise a first projection and a second projection, and a height of the first projection is longer than a height of the second projection, when the topsheet is viewed in a plan view, a second projection region which comprises the second projection surrounded by a plurality of the first projections is formed, and when the topsheet is viewed in a plan view, the joined regions comprise an inner joined region in the second projection region, wherein the plurality of the joined regions comprise first joined regions, and the first joined regions comprise the inner joined region disposed in the second projection region, and an outer joined region disposed outside the second projection region, and each of the inner joined region and the outer joined region is formed of one joined portion having a square shape as viewed in a plan view, and each side of the inner joined region and each side of the outer joined region are aligned with a first direction or a second direction, wherein the plurality of the joined regions comprise second joined regions each of which is formed of two second joined portions, and an outer shape of each of the second joined portions as viewed in a plan view is formed into a square shape, the square shape having a shape and size identical to a shape and size of the first joined regions, and each side of the second joined portions is aligned with the first direction or the second direction, wherein the plurality of the joined regions comprise third joined regions each of which is formed of one joined portion having a rectangular shape as viewed in a plan view, a longitudinal direction of each of the third joined regions is aligned with the first direction, and a short direction of each of the third joined regions is aligned with the second direction, and the first joined regions form a first joined region row where the inner joined region and the outer joined region are alternately arranged in one row along the first direction at a fixed pitch, a plurality of the second joined regions form a second joined region row where the second joined regions are arranged in one row along the first direction at a fixed pitch, a plurality of the third joined regions form a third joined region first row where the third joined regions are arranged in one row along the first direction at a fixed pitch, and the plurality of the third joined regions form a third joined region second row where the third joined regions are displaced from the third joined region first row in the first direction by a half pitch, and the topsheet comprises, using the first joined region row as a center, the second joined region row, the third joined region first row, the second joined region row, the third joined region second row, the second joined region row, the third joined region first row, and the second joined region row which are arranged at fixed intervals in the second direction, and which are arranged repeatedly in the second direction in this order.
