A manufacturing apparatus for an absorbent body is provided. The manufacturing apparatus includes: a mold member that includes a mold formed in a depressed shape on a predetermined face and moves the mold along a first direction intersecting a width direction of the predetermined face a supply duct that is arranged at a predetermined position in the first direction and supply 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 to the supply opening with the predetermined face in between, and that forms a partitioned closed space together with the predetermined face and an air intake duct that sucks air in the closed space from a suction opening in order to set a pressure in the closed space to negative pressure. When the mold passes a position of the supply opening, the air in the supply duct is sucked from a suction hole of a bottom section of the mold to the closed space and the liquid absorbent material in the air is deposited into the mold, and thereby the absorbent body is formed. The suction opening of the air intake duct is arranged opposite to the predetermined face in the closed space. Concerning at least a portion that is included in the air intake duct and is housed in the closed space, a central-axis direction of the portion has a component parallel to a moving direction in which the mold is moving at a central position of the suction opening.
