PROBLEM TO BE SOLVED: To suppress the occurrence of sagging in a waist circumference portion while improving the flexibility of the waist circumference portion of an absorbent article. An absorbent article (1) having a pair of waist circumference portions (20, 30) and an absorbent body (10), wherein the waist circumference portion (20) is a pair of sheets (21, 22). ) And a plurality of elastic members (23), each elastic member (23) is continuously arranged from one end to the other end in the width direction of the waist circumference portion (20), and is in the width direction. It has end fixing portions (40) at both ends, and a plurality of telescopic members (23) are fixed to a pair of sheets (21, 22) inside the end fixing portion (40) in the width direction. A fixed portion (52) in which a first telescopic member (231a) having a non-fixed portion (51) and a region overlapping the non-fixed portion (51) in the width direction are fixed to a pair of sheets (21, 22). The length of the non-fixed portion (51) is longer than the length of the absorbent main body (10) in the width direction with the second telescopic member (231b).
