Abstract
An absorbent body in which a larger amount of a granular absorbent substance penetrates into the inside of a fiber sheet is produced. A fiber sheet having napped one main surface is supplied to a conveying device and conveyed while the other main surface of the fiber sheet is being sucked through a conveyance surface. A granular absorbent substance is sprayed onto the napped one main surface of the fiber sheet to cause the substance to penetrate into the inside of the fiber sheet in a suction section. A pressure difference increasing device 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 air from flowing through the fiber sheet inward from the conveyance surface to increase the pressure difference between the conveyance surface side and the opposite side of the fiber sheet.
