Provided is an absorbent body (1) for body fluid-absorbing articles, that is both soft and strong. The absorbent body (1) for body fluid-absorbing articles: includes 100 parts by mass cellulose-based water-absorbent fibers (3) and 7.5-100 parts by mass thermoplastic resin fibers (4)； and has an apparent density of 0.06-0.14 g/cm3. The thermoplastic resin fibers (4) having a fiber length longer than the cellulose-based water-absorbent fibers (3) are twisted together. The absorbent body (1) has compressed sections (2) arranged in a repeated pattern. The compressed sections (2) are characterized by having a Gurley bending resistance of no more than 1 mN as a result of not being fused.
