PROBLEM TO BE SOLVED: To provide a manufacturing method of an absorbent body capable of efficiently absorbing a body fluid, having an excellent dry feeling, and efficiently manufacturing a laminated body absorbent in which the body fluid does not leak. SOLUTION: The method for manufacturing an absorbent body 100 of the present invention draws a nonwoven fabric piece 10b of synthetic fibers and a hydrophilic fiber 10a conveyed by an air flow into the accumulating concave portion 21 while sucking the accumulating concave portion 21 to be conveyed. Accumulate. The collecting recess 21 has a low suction recess 21T and a high suction recess 21K having a suction force higher than that of the low suction recess 21T. The non-woven fabric piece 10b is supplied to the accumulating concave portion 21 to accumulate the non-woven fabric piece 10b in the accumulating concave portion 21. After accumulating the nonwoven fabric pieces 10b, the hydrophilic fibers 10a are supplied to the accumulating recesses 21 to accumulate the hydrophilic fibers 10a in the accumulating recesses 21. Then, a larger amount of the nonwoven fabric pieces 10b are accumulated in the high suction recess 21K than in the low suction recess 21T. [Selection diagram] Fig. 3【課題】体液を高速吸収でき、ドライ感に優れ、体液が漏れ難い積層構造の吸収体を効率的に製造できる吸収体の製造方法を提供すること。【解決手段】本発明の吸収体１００の製造方法は、搬送する集積用凹部２１を吸引しながら、集積用凹部２１に、空気流により搬送された合成繊維の不織布片１０ｂ及び親水性繊維１０ａを集積させる。集積用凹部２１は低吸引凹部２１Ｔと、低吸引凹部２１Ｔよりも吸引力が高い高吸引凹部２１Ｋとを有する。不織布片１０ｂを集積用凹部２１に供給して、集積用凹部２１内に不織布片１０ｂを集積させる。不織布片１０ｂの集積後に親水性繊維１０ａを集積用凹部２１に供給して、集積用凹部２１内に親水性繊維１０ａを集積させる。そして、高吸引凹部２１Ｋ内に低吸引凹部２１Ｔ内よりも多量の不織布片１０ｂを集積させる。【選択図】図３
