[Problem] To inhibit defective forming of a high compression part, and prevent a surface sheet from being torn. [Solution] In a sanitary napkin (1), a low compression part (15) and a high compression part (16, 17, 18) are formed on the bottom surface of a compression groove (10) that is recessed from the skin contact surface side. The high compression part includes: regularly-arranged high compression parts (16) that are regularly arranged along the length direction of the compression groove (10)； large-area high compression parts (17) that are irregularly arranged in the compression groove (10) and that are each formed so as to have a larger area than each of the regularly-arranged high compression parts (16)； and auxiliary high compression parts (18) that are each arranged at a position closer to one end side, in the napkin length direction, of the corresponding one of the large-area high compression parts (17) with the low compression part (15) interposed between the auxiliary high compression part and the large-area high compression part, and that are each formed so as to be wider than the large-area high compression part (17) in such a manner as to receive a portion, of the large-area high compression part (17), at the one end side thereof in the napkin length direction.Le problème abordé par la présente invention est d'inhiber la formation de défauts dans une partie à forte compression, et d'empêcher la déchirure d'une feuille de surface. La solution selon l'invention porte sur une serviette hygiénique (1) comportant une partie à faible compression (15) et une partie à forte compression (16, 17, 18) formées sur la surface inférieure d'une rainure de compression (10) qui forme un creux côté surface en contact avec la peau. La partie à forte compression comprend : des parties à forte compression (16) qui sont régulièrement réparties dans le sens de la longueur de la rainure de compression (10)； des parties à forte compression de grande surface (17) qui sont irré
