Abstract
An absorbent article having a substantially oblong shape, which is superior in liquid-proof performance and fitness, includes a liquid permeable top sheet, a back sheet, an absorbent body having elasticity disposed between the top sheet and the back sheet, and a compressed portion compressing the top sheet and the absorbent body. The compressed portion is disposed continuously to form a protrusion in a longitudinal direction to define a substantially U shape. The absorbent portion has a low elasticity portion, disposed on one part of the absorbent body, and formed so that elasticity weakens when compression to a prescribed thickness is carried out. The low elasticity portion is disposed in the vicinity of an end protruding the most in the longitudinal direction of the substantially U shape.
