The absorbent body (100) of the present invention includes: fiber masses (11) comprising fibers (11F) that include thermoplastic fibers; and absorbent fibers (12F). The absorbent body (100) has, in the planar direction thereof, a first region (15) in which a plurality of the fiber masses (11) is fused to each other and a second region (16) in which a plurality of the fiber masses (11) is entangled without being fused. The fiber masses (11) and absorbent fibers (12F) are also entangled with each other in at least the second region (16). The fiber masses (11) have a body portion (110) defined by two opposing base surfaces (111) and a skeletal surface (112) intersecting both base surfaces (111).本發明之吸收體(100)包含:纖維塊(11),其包含含有熱塑性纖維之纖維(11F)而成;及吸水性纖維(12F);於其面方向具有複數個纖維塊(11)彼此相互熔合之第1區域(15)、及複數個纖維塊(11)彼此不熔合而交絡之第2區域(16)。又,至少於第2區域(16)中,纖維塊(11)與吸水性纖維(12F)相互交絡。纖維塊(11)具有由相對向之2個基本面(111)及與兩基本面(111)交叉之骨架面(112)劃分形成之本體部(110)。
