[PROBLEMS] To provide a fiber accumulating apparatus capable of suppressing the deviation of the weight of an absorbent body by stabilizing the profile of the absorbent body a manufacturing method for the absorbent body using the fiber accumulating apparatus and an absorbent article having the absorbent body manufactured by the method.[MEANS FOR SOLVIMG THE PROBLEMS]This fiber accumulating apparatus comprises a fiber accumulating drum (1) having a perforated body (10) that accumulates an absorbent body raw material (S) on its surface by suction from the internal side. The perforated body (10) has a large number of sucking pores (10a), (10a),... formed therein and comprises a perforated plate (10A) making up the surface and a flow-adjuster (10B) that is disposed on the internal side of the perforated plate (10A) and flow-adjusts an air flow. The perforated plate (10A) and flow-adjuster (10B) are integrally constructed.
