A sensor-equipped wearable article comprising a urination sensor that detects urination and that is attached to an outside surface of one sheet among a plurality of sheets constituting the wearable article, wherein: the urination sensor includes a printing substrate formed of a resin film, and a plurality of planar printed electrodes that constitute a sensor element and that are made by an electroconductive ink applied to a surface of the printing substrate; the urination sensor is provided with a section where the printing substrate is not present, the section being provided between the plurality of planar printed electrodes; the urination sensor, including the section where the printing substrate is not present, is covered by a cover sheet in which an adhesive is applied to a nonwoven fabric; the printing substrate is bonded to the one sheet by the adhesive applied to the cover sheet in a manner that the printed electrodes face the surface of the one sheet; the one sheet is an electrically insulating, sparingly liquid-permeable substrate; the printing substrate is an electrically insulating substrate; the plurality of planar printed electrodes are covered by the one sheet and the printing substrate; and non-application sections are present on the surface of the cover sheet to which the adhesive is applied, and the section where the printing substrate is not present forms an air-passage opening which retains an air-passage function with the non-application sections.
