PROBLEM TO BE SOLVED: To provide a sanitary napkin which makes the back flap part disposed expanding along the inner side of an underwear easily follow body deformation, gives no sense of incongruity to the body, and hardly develops wrinkle or twisting. SOLUTION: The back flap part 25 extending to both left and right sides from the rear of the body part 5 of the sanitary napkin 1 is constituted of a second sheet on the clothes side and a first sheet on the skin side. A wavelike deforming part 45 of which the ridge part 46 and the valley part 47 extend in the lateral direction is formed and a non-deforming part 48 extending in the vertical direction in a straight line is formed on the first sheet. By forming the wavelike deforming part 45 and the non-deforming part 48, the back flap part 25 can be flexibly deformed following the body. COPYRIGHT: (C)2006,JPO&NCIPI
