According to a method of producing an absorbent member (3) of the present invention including a depositing step of depositing raw material of absorbent member fed along with an air stream to a recess portion (22) which is arranged at an outer circumferential face of a rotatable drum (2) by suctioning and a pressing step of pressing and compressing a deposited aggregate (32) released from the inside of the recess portion (22), the recess portion (22) includes a suction portion (23) which is formed of a porous plate (26) to perform suctioning from a bottom face and a non-suction portion (24) having an air-impermeable bottom face not to perform suctioning from the bottom face while depth of the non-suction portion (24) from the outer circumferential face of the rotatable drum is shallower than depth of the suction portion (23) from the outer circumferential face of the rotatable drum, the raw material is deposited into the recess portion (22) in the depositing step, and the absorbent member (3) having a high density portion and a low density portion with mutually different density is obtained by pressing the deposited aggregate (32) released from the recess portion (22) in the pressing step.
