[Problem]To strongly join a side sheet and a front-surface sheet to prevent detachment, and to improve the feel against the skin by making fit flexibly to a body.[Means for Solving the Problem]On a skin side of a laminated part of a side sheet 7 and a liquid permeable front-surface sheet 3, a side emboss that sinks in toward a non-skin side and is made by fusing the side sheet 7 and the liquid permeable front-surface sheet 3 is formed. The side emboss 10 is comprised of a plurality of large embosses 11, 11 formed to have a relatively larger area that are arranged to align linearly along the longitudinal direction of a sanitary napkin 1 with equal intervals, and between the adjacent large embosses 11, 11, a plurality of small embosses 12 ... formed to have a relatively small area that are arranged in a wave-like shape along the longitudinal direction of the sanitary napkin 1 with intervals, separated from the large embosses 11.
