A absorbent member manufacturing method of the invention is a method for manufacturing an absorbent member (100) including synthetic fibers (10b). The method involves: a transporting step of transporting a plurality of sheet fragments (10bh) including synthetic fibers (10b) to an accumulating depression (41) by using a duct 3； an accumulating step of accumulating, in the accumulating depression (41), the plurality of sheet fragments (10bh) transported in the transporting step, and forming an accumulation (100a′；) which is a constituent member of the absorbent member (100)； and a pressing step of pressing the accumulation (100a′；) over its entirety in the thickness direction.
