A crushing step of crushing the tip of the pulp sheet (1) to produce fibrous pulp which is a material of an absorber, and a cutting step of cutting the leading pulp sheet (1p) and the trailing pulp sheet (1f). It is provided with a splicing step of splicing a pulp sheet (1p) and a trailing pulp sheet (1f) to produce a seamless pulp sheet, and the seamless pulp sheet is arranged in the order of the leading pulp sheet (1p) and the trailing pulp sheet (1f). An absorber manufacturing method for crushing, in which the leading pulp sheet (1p) and the trailing pulp sheet (1f) are cut diagonally so as to have the same degree of inclination, and the length of the diagonal cutting line in the feeding direction ( A cutting step of cutting so that La) is longer than the shortest distance (Lb) from the support position (20a) to the movement locus of the cutting edge of the crushing blade (31b), and the rear end cutting line (CLp) and the tip cutting line. It is characterized by including a splicing step of forming a seamless pulp sheet by splicing (CLf) in a butted state.パルプシート（１）の先端を粉砕して、吸収体の材料である繊維状パルプを生成する粉砕工程と、先行パルプシート（１ｐ）と後行パルプシート（１ｆ）を切断する切断工程と、先行パルプシート（１ｐ）と後行パルプシート（１ｆ）を継いで継ぎ目付きパルプシートを生成する継ぎ工程とを備え、継ぎ目付きパルプシートを先行パルプシート（１ｐ）、後行パルプシート（１ｆ）の順に粉砕する吸収体製造方法であって、先行パルプシート（１ｐ）と後行パルプシート（１ｆ）を傾き度合いが同じになるように斜めに切断し、かつ、送り方向における斜め切断線の長さ（Ｌａ）が支持位置（２０ａ）から粉砕刃（３１ｂ）の刃先の移動軌跡までの最短距離（Ｌｂ）より長くなるように切断する切断工程と、後端部切断線（ＣＬｐ）と先端部切断線（ＣＬｆ）を突き合わせた状態で継いで継ぎ目付きパルプシートを生成する継ぎ工程とを備えることを特徴とする。
