A device for manufacturing an absorber (1) having a first basis weight portion (1L) in which a liquid absorbent material (2) is deposited at a first basis weight and a second basis weight portion (1H) in which the liquid absorbent material (2) is deposited at a basis weight greater than the first basis weight. The present invention has: a suction deposition device (11) for producing a continuous body (1r) of an absorber that is continuous in a prescribed direction by suctioning in air via a plurality of intake holes (21h) in an intake surface (21a) and thereby suctioning in and depositing the liquid absorbent material (2) onto the intake surface (21a) and a cutting device (61) for producing the absorber (1) by cutting the continuous body (1r) of the absorber at boundaries (21BL) of the absorbent material (1) that are set on the continuous body (1r) of the absorber at intervals along the prescribed direction. The intake surface (21a) has a first suctioning region (AL) in which the intake holes (21h) are formed at a first ratio and a second intake region (AH) in which the intake holes (21h) are formed at a second ratio higher than the first ratio. The second absorbent region (AH) includes the boundaries (21BL).
