A manufacturing apparatus for an absorbent body is provided.The manufacturing apparatus includes: a mold member thatincludes a mold formed in a depressed shape on a predeterminedface and moves the mold along a first direction intersecting awidth direction of the predetermined face a supply duct that isarranged at a predetermined position in the first direction andsupply air towards the predetermined face from a supply opening,the air containing a liquid absorbent material a partitioned-space-forming member that is disposed at a position opposite tothe supply opening with the predetermined face in between, andthat forms a partitioned closed space together with thepredetermined face and an air intake duct that sucks air in theclosed space from a suction opening in order to set a pressurein the closed space to negative pressure. When the mold passesa position of the supply opening, the air in the supply duct issucked from a suction hole of a bottom section of the mold tothe closed space and the liquid absorbent material in the air isdeposited into the mold, and thereby the absorbent body isformed. The suction opening of the air intake duct is arrangedopposite to the predetermined face in the closed space.Concerning at least a portion that is included in the air intakeduct and is housed in the closed space, a central-axis directionof the portion has a component parallel to a moving direction inwhich the mold is moving at a central position of the suctionopening.
