[Problem] To provide a solid gather structure that is free from an uncomfortable feeling when wearing, is high in a body liquid blocking effect, and blocks from falling down on the inside even in a thin sanitary towel.[Means for Solving the Problem] When a side nonwoven fabric 7 is folded back in a folded state, an outside extended stock 7c that has a lower layer side cuff surface 7a and an upper layer side cuff surface 7b and in which the upper layer side cuff surface 7b is extended outward than an absorber side edge 4a on the upper layer side cuff surface 7b is disposed, an inside elastic member 8 is disposed in an intermediate portion in a width direction corresponding to a non-joint area 14 of the upper layer side cuff surface 7b, and when standing-up toward a skin side with an inside edge portion 13a of a joint area 13 as a base in a standing state, a portion between from the inside elastic member 8 to the inside edge portion 13a of a joint area works as a standing wall Gc and an outside portion than the inside elastic member 8 works as a skin-abutting surface Gd when wearing, and a portion that works as a skin-abutting surface Gd moves outward in a towel width direction in the standing state than in the folded state.
