A liquid absorbent fiber (6) and a superabsorbent polymer (SAP) are deposited in the recess (71) to form the absorbent body (1), and the liquid absorbency toward the recess (71). A supply part (20) for supplying the fibers (6) and the superabsorbent polymer (SAP), the recess part (71) is provided with a protrusion part (80) protruding from the bottom surface and having an inclined surface (82). In the cross section orthogonal to the ridgeline of (80), the angle of the inclined surface (82) with respect to the plane parallel to the bottom surface is larger than the angle of repose of the superabsorbent polymer (SAP) and smaller than 90 degrees (1) Manufacturing equipment (10).液体吸収性繊維（６）及び高吸収性ポリマー（ＳＡＰ）を凹部（７１）に堆積させて、吸収体（１）を成形する成形部（３０）と、凹部（７１）に向けて液体吸収性繊維（６）及び高吸収性ポリマー（ＳＡＰ）を供給する供給部（２０）とを備え、凹部（７１）は底面から突出し且つ傾斜面（８２）を有する突出部（８０）を備え、突出部（８０）の稜線と直交する断面において、底面に平行な面に対する傾斜面（８２）の角度が、高吸収性ポリマー（ＳＡＰ）の安息角よりも大きく、９０度よりも小さい吸収体（１）の製造装置（１０）。
