Manufacture of an absorber that forms an absorber with shorter dimension in the transport direction than dimension in the transverse directionIn the manufacturing method, when cutting the absorbent body continuum in the transverse direction, cuttingEven if the position is shifted, it makes it difficult for the consumer to recognize the positional deviation. A method of manufacturing an absorbent body for an absorbent article, wherein the material of the absorbent body (3)A preparation step of preparing an extending absorber continuous body (50) a stepWhile conveying it in the feeding direction, is larger than the dimension in the transverse direction orthogonal to the conveying direction in the conveying directionAnd a cutting step of cutting along the transverse direction so as to form an absorbent body having a short dimension, wherein the transverse edge portion (50 b) of the absorbent body continuation convexly protrudes in the transverse direction A convex curved region having a curved outer edge and a concave curved region having a concave curved outer edge with respect to an outer side in a transverse direction, wherein the convex curved region and the concave curved region are convex And the cutting step includes a step of cutting the absorbent body continuum in the concave curved region.横断方向の寸法よりも搬送方向の寸法が短い吸収体を形成する吸収体の製造方法において、吸収体連続体を横断方向に沿って切断するときに、切断の位置がずれても、その位置ずれを消費者に認識し難くする。 吸収性物品用の吸収体の製造方法であって、吸収体(3)の材料が帯状に延在する吸収体連続体(50)を準備する準備工程と、吸収体連続体を、搬送方向に搬送しつつ、搬送方向に直交する横断方向の寸法よりも搬送方向の寸法が短い吸収体を形成するように、横断方向に沿って切断する切断工程と、を備え、吸収体連続体の横断方向の端延部(50b)は、横断方向の外側に対して凸に湾曲した外縁を有する凸湾曲領域(52)と、横断方向の外側に対して凹に湾曲した外縁を有する凹湾曲領域(53)と、を有し、凸湾曲領域と凹湾曲領域とが搬送方向に沿って交互に配置されており、切断工程は、吸収体連続体を、凹湾曲領域において切断する工程を含む。
