The absorbent article is further provided with a stretchable waist member (11) disposed within the laminate in a manner enabling stretching in the width direction W, and a pair of stretchable side members (7, 7) formed on the peripheral edge of the laminate in a manner enabling stretching in the width direction. One member and the other member of the pair of stretchable side members are formed, respectively, on one end and the other end of the laminate in the width direction. The stretchable waist member overlaps with each of the pair of stretchable side members in the lengthwise direction, is disposed further on the non-skin side than the absorbent body in the thickness direction, and overlaps with the absorbent body in the thickness direction but is not joined thereto.
