PROBLEM TO BE SOLVED: To suppress misalignment of an absorbent core while improving the flexibility of a waist circumference portion of an absorbent article. SOLUTION: In an absorbent article (1), at least one (20) of a pair of waist circumferences has a pair of sheets (21, 22) and an elastic member (231), and each elastic member (231). ) Is a pair of end fixing portions that are continuous from one end in the width direction to the other end of one waist circumference portion (20) and both ends in the width direction are fixed to a pair of sheets (21, 22). The plurality of telescopic members (231) having (50) have a non-fixed portion (51) which is not fixed to a pair of sheets (21, 22) inside the end fixed portion (50) in the width direction. It has a first telescopic member (231a) and a central fixing portion (52) fixed to a pair of sheets (21, 22) over at least the entire area overlapping the absorbent core (11A) in the width direction. It also has a second telescopic member (231b) arranged in a region overlapping the absorbent body (10) in the longitudinal direction.
