Provided is an absorbent article which has improved comfort and suppresses irritation to the skin due to the side bonding portions where the forward waist area and the rear waist area are bonded. This disposable diaper (1) is an underpants-type absorbent article. An exterior body is provided with leg-encircling rear elastic members (57) arranged along the opening around the leg of the rear waste area, and leg-encircling front elastic members (51) arranged along the opening around the legs in the front waist area. In a stretched state in which the leg-encircling front elastic members (51) and the leg-encircling rear elastic members (57) are stretched, the angle formed between the edge leg-encircling rear elastic member (571), which is positioned on the side of the opening around the legs, and an imaginary line (FL1) extending in the width direction, is greater than the angle formed by the edge leg-encircling front elastic member (511), which is positioned on the side of the opening around the legs and the imaginary line (FL1), and the stretching force of the width direction on the edge leg-encircling front elastic member is higher than the stretching force in the width direction of the edge leg-encircling rear elastic member.
