A method of manufacturing an absorbent article including an absorber having: a longitudinal direction adapted to extend from a body foreside toward a body backside of a wearer; a widthwise direction perpendicular to the longitudinal direction; an inner side adapted to face the wearer; and an outer side adapted to face away from the wearer; an elastic member elongated in an extended state in the longitudinal direction and disposed at the outer side of the absorber; and a first sheet member and second sheet member disposed at the outer side of the absorber, the elastic member being disposed between the first sheet member and second sheet member, the method comprising: a first step of applying an adhesive agent to the elastic member while conveying, in a conveyance direction, the elastic member in a stretched state, and alternately forming, in the conveyance direction, an application region in which the adhesive agent is applied to the elastic member and a non-application region in which the adhesive agent is not applied to the elastic member; a second step of applying a further adhesive agent to a face, which is opposite to the elastic member, of the first sheet member so that the further adhesive agent permeates the first sheet member in a thickness direction of the first sheet member, the second step applying the further adhesive agent to at least a position which overlaps with the non-application region; and a third step of cutting the elastic member in the non-application region and, in the application region, disposing the elastic member in a stretched state.

A method of manufacturing an absorbent article including an absorber having an inner side adapted to face the wearer, and an outer side adapted to face away from the wearer; first and second sheet members disposed at the outer side of the absorber; and an elastic member disposed at the outer side of the absorber and between the first and second sheet members; said method comprising: conveying, in a conveyance direction, an elastic continuous body constituting the elastic member in a stretched state; applying a first adhesive agent to the elastic continuous body to alternately form, in the conveyance direction, an application region in which the first adhesive agent is applied to the elastic continuous body and a non-application region in which the first adhesive agent is not applied to the elastic continuous body; conveying, in the conveyance direction, a covering continuous body constituting the first sheet member and having a first face facing the elastic continuous body and a second face facing away from the elastic continuous body; applying a second adhesive agent to the first face of the covering continuous body; joining the covering continuous body and the elastic continuous body to a main body continuous body constituting the absorber and the second sheet member; applying a third adhesive agent to the second face of the covering continuous body at least at a position overlapping the non-application region of the elastic continuous body, wherein the third adhesive agent permeates the covering continuous body in a thickness direction of the covering continuous body; and cutting the elastic continuous body in the non-application region to obtain the elastic member in the application region in the stretched state.
