An absorbent body producing method, comprising: a first step in which a fiber sheet having one main surface side thereof napped is supplied to a conveying device and conveyed while an other main surface side of the fiber sheet is being sucked through a conveyance surface of the conveying device; and a second step in which a granular absorbent substance capable of absorbing and holding liquid is sprayed onto the napped one main surface of the fiber sheet so that the granular absorbent substance is disposed only in a single suction section where air is continuously sucked through the other main surface of the fiber sheet and the conveyance surface and the sprayed absorbent substance is caused to penetrate into an inside of the fiber sheet only in the single suction section, wherein at the first and second steps, a pressure difference increasing means is provided that faces the one main surface of the fiber sheet sprayed with the absorbent substance and being conveyed in the suction section and that suppresses an air flow penetrating the fiber sheet to move inward from the conveyance surface to thereby increase the pressure difference between the conveyance surface side and the opposite side of the fiber sheet.
