[Problem] To make it easier to draw in a body fluid while suppressing diffusion of liquid on a surface and to reduce anxiety about leakage. [Solution] A sanitary napkin 1 in which a polymer sheet 4 that comprises a superabsorbent polymer disposed between two layers of sheets is interposed between a liquid-permeable obverse-surface sheet 3 and a liquid-impermeable rear-surface sheet 2. A large number of concave portions 10, 10… that indent into the non-skin side and that are surrounded by ridge-like convex portions 11, which produce a continuous perimeter, form a continuous lattice pattern in a region on the skin-side surface of the liquid-permeable obverse-surface sheet 3 that includes a body fluid discharge site.
