An absorbent article having: a longitudinal direction extending to a body front side and a body rear side of a wearer; a widthwise direction perpendicular to the longitudinal direction; an inner direction for facing a wearer; an outer direction which is opposite to the inner direction, a crotch region which is adapted to be in contact with a crotch of the wearer; a front waistline region which is disposed forward of the crotch region, and is adapted to be in contact with a waistline of the wearer; a rear waistline region which is disposed rearward of the crotch region, and is adapted to be in contact with the waistline of the wearer, an absorber which is disposed at least at a center in a widthwise direction of the crotch region; an exterior body which is positioned at the outer direction side of the absorber, and is disposed on a surface at a non-skin contact side of the absorbent article; and leg opening units disposed along a leg-line of the wearer and formed in the crotch region, wherein the exterior body has an edge part which is forming a part of the leg opening unit and is positioned outboard of the absorber in a widthwise direction, a rear end of the absorber is positioned in the crotch region, a waistline elastic member to expand and contract in the widthwise direction in the waistline region and a leg-holes elastic member to expand and contract along the leg opening unit are disposed at the exterior body, the leg-holes elastic member has: one pair of first expanding and contracting units which is positioned inside in the longitudinal direction as the first extending and contracting units go to a center in a widthwise direction and which is positioned outboard of the absorber in the widthwise direction; and a second expanding and contracting unit which is positioned in an absorber disposition region in which the absorber is disposed between the first expanding and contracting units, and an edge part of the exterior body extends across the end of the absorber in the widthwise direction from the outside in the widthwise direction to an inside in a widthwise direction as the edge part goes to the inside in the inside in the longitudinal direction, wherein a crotch elastic member to expand and contract in the widthwise direction is disposed in the crotch region, and an expansion stress of the crotch elastic member is lower than an expansion stress of the leg-holes elastic member and is lower than an expansion stress of the waistline elastic member. a longitudinal direction extending to a body front side and a body rear side of a wearer;
