Abstract
(Object) To prevent a high compression portion from being defectively formed and also a top sheet from being torn. (Means of Achieving the Object) A sanitary napkin (1) in which a low compression portion (15) and a high compression portion (16, 17, 18) are formed on a bottom surface of a compressed groove (10) that is recessed from a skin contact surface side. The high compression portion includes regularly-arranged high compression portions (16) that are regularly arranged in a longitudinal direction of the compressed groove (10), a large-area high compression portion (17) that is irregularly arranged in the compressed groove (10) and has an area larger than an area of each of the regularly-arranged high compression portions (16), and an auxiliary high compression portion (18) that is arranged at one side, in a longitudinal direction of the napkin, of the large-area high compression portion (17) through the low compression portion (15) so as to surround the one side, in the longitudinal direction of the napkin, of the large-area high compression portion (17).
