In the disclosed absorbent article (1), in a first region (X), a first elastic member (100) extends linearly in the widthwise direction (W), in a second region (Y), a second elastic member (91) extends linearly in the widthwise direction (W), the elongational stress of the first elastic member (100) is greater than the elongational stress of the second elastic member (91), and the length (W1) in the widthwise direction of the joining region (H) that is of both the main body (2) of an absorbent body and a chassis (3) in the first region (X) is configured in a manner so as to be shorter than the length (W2) in the widthwise direction of the joining region (H) that is of both the main body (2) of the absorbent body and the chassis (3) in the second region (Y).
