An absorbent article comprising: a longitudinal direction which extends between a body foreside and a body rearside of a wearer; a widthwise direction perpendicular to the longitudinal direction; an inner direction which is oriented to the wearer; an outer direction which is oriented to an opposite to the inner direction; a crotch region which is applied for a crotch of the wearer; a front waistline region which is disposed at a front side of the crotch region; a rear waistline region which is disposed at a rear side of the crotch region; an absorber which is disposed at least in the crotch region; an elastic member which is disposed in an extended state in the longitudinal direction in the outer direction than the absorber; and a sheet member which is disposed on a face of the outer direction of the elastic member, and which abuts against the elastic member, wherein the sheet member is disposed so as to cover: a stretch region in which the elastic member is disposed in a stretched state in the longitudinal direction; and a non-stretch region in which the elastic member is disposed in a non-stretched state, wherein a first adhesive agent is disposed to an inner surface or an outer surface of the elastic member in the stretch region, a second adhesive agent is disposed between the sheet member and the elastic member in the stretched state in the stretch region, the sheet member is joined with the elastic member, wherein a third adhesive agent is disposed to an outer surface of the sheet member at least in the non-stretch region, and wherein a fourth adhesive agent permeated by the third adhesive agent that is applied to an outer surface of the sheet member is disposed on an inner surface of the sheet member, basis weight of the fourth adhesive agent that is disposed on an inner surface of the sheet member is smaller than basis weight of the first adhesive agent that is disposed to an inner surface or an outer surface of the elastic member in the stretch region.
