PROBLEM TO BE SOLVED: To increase stiffness and tension of a standing part of a side sheet, and prevent opening of an unnecessary hole in the side sheet.SOLUTION: There are included a side sheet arranged on both sides in the width direction of an absorbent body, and an elastic member 30 fixed to the side sheet. The side sheet has an overlapping part 21 in which a plurality of sheet layers are overlapped in the inside in the width direction. The overlapping part of the side sheet has a standing part 24 standing from the absorbent body, and a fixation part 25 fixed to the absorbent body. The standing part 24 is connected with the sheet layer by a plurality of first embossment 40, and the fixation part 25 is connected with the sheet layer by a plurality of second embossment 50. At least part of a first connection area 41 is not fixed to the absorbent body, and stands when the elastic member 30 shrinks. At least part of a second connection area 51 is fixed to the absorbent body.SELECTED DRAWING: Figure 3
