An absorptive body (10) having suitably formed openings (13). The absorptive body (10) is placed between a liquid permeable front side sheet and a liquid impermeable rear side sheet and can absorb liquid. The absorptive body (10) has high-rigidity regions (11) and a low-rigidity region (12) that is the remaining region. An opening (13) is formed in each of the high-rigidity regions (11) by providing a cut in the high-rigidity region (11) and expanding the cut in width.
