In an undershort pants-type absorbent article (1), pairs of bonding parts (2) are disposed at the front side and the rear side so as to bond an absorbent body (10) that is equipped with an absorbent material (12) and that is disposed along the lengthwise direction and a pair of belt parts (20) that are expandable/contractable in the lateral direction. A portion between the rear-side pair of bonding parts (2) does not expand/contract in the lateral direction. An elastic part (42) that is expandable/contractable in the lengthwise direction is disposed at a location farther away from the skin of the wearer than the absorbent material (12), and the elastic part (42) is disposed, at least on the rear side, at the central part in the lateral direction of the absorbent body (10).
