PROBLEM TO BE SOLVED: To enhance cutting property when forming an absorber by cutting the absorber from a continuous body of the absorber.SOLUTION: A manufacturing device of an absorber related to an absorbent article is a device for manufacturing an absorber having a first basis weight part in which a liquid absorbent material is deposited with a first basis weight and a second basis weight part in which the second basis weight part is deposited with a basis weight higher than the first basis weight, and comprises: a suction and deposition device for forming a continuous body of the absorber continuous in a predetermined direction by sucking air from a plurality of suction ports on a suction surface, and sucking and depositing the liquid absorbent material on the suction surface； and a cutting device for forming the absorber by cutting the continuous body of the absorber at boundary positions of the absorber established on the continuous body of the absorber with space in the predetermined direction. The suction surface has a first suction area where the suction ports are formed with a first opening ratio, and a second suction area where the suction ports are formed with a second opening ratio higher than the first opening ratio. The boundary positions are included in the second suction area.【課題】吸収体を吸収体の連続体から切断して生成する際の切断性を高める。【解決手段】液体吸収性材料が第１坪量で堆積した第１坪量部分と、前記第１坪量よりも高い坪量で堆積した第２坪量部分とを有した吸収体を製造する装置である。吸引面の複数の吸気口から吸気をして前記吸引面に前記液体吸収性材料を吸引して堆積させることによって、所定方向に連続した吸収体の連続体を生成する吸引堆積装置と、前記所定方向に間隔をあけて前記吸収体の連続体上に設定される前記吸収体の境界位置で前記吸収体の連続体を切断することにより、前記吸収体を生成する切断装置と、を有する。前記吸引面は、第１開口率で前記吸気口が形成された第１吸引領域と、前記第１開口率よりも高い第２開口率で前記吸気口が形成された第２吸引領域とを有する。前記第２吸引領域に前記境界位置が含まれている。【選択図】図５
