PROBLEM TO BE SOLVED: To prevent gel blocking while achieving thinning and also securing an amount of water absorption.SOLUTION: A sanitary napkin 1 includes a polymer sheet 4 in which a high-water absorbent polymer 12 is included between two layered sheets 10 and 11, and has a multilayer structure where the plurality of polymer sheets 4 are laminated. Each of the polymer sheets 4 is formed with a polymer arrangement area 13 in which the high-water absorbent polymer 12 is arranged, and a polymer non-arrangement area 14 in which the high-water absorbent polymer 12 is not arranged. The polymer arrangement areas 13 are provided in a position in which they are not overlapped in the thickness direction in at least between the polymer sheets 4 adjacent in the lamination direction, and the two layered sheets 10 and 11 are connected by a compressed groove 15 provided in a part in which the high-water absorbent polymer 12 is not arranged.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2017,JPO&INPIT【課題】薄型化を図りながらも、吸水量を確保しつつ、ゲルブロッキングを防止する。【解決手段】2層のシート10、11間に高吸水性ポリマー12が介在されたポリマーシート4を備えた生理用ナプキン1である。ポリマーシート4が複数積層された多層構造を有し、各ポリマーシート4に、高吸水性ポリマー12が配置されたポリマー配置領域13と、高吸水性ポリマー12が配置されないポリマー無配置領域14とが形成され、少なくとも積層方向に隣接するポリマーシート4間において、ポリマー配置領域13同士が厚み方向に重ならない位置に設けられるとともに、前記2層のシート10、11が高吸水性ポリマー12が配置されない部分に設けられた圧搾溝15によって接合されている。【選択図】図4
