PROBLEM TO BE SOLVED: To improve adhesion to the cleavage of buttocks and to prevent rear leakage.SOLUTION: Intermittent concave grooves 20, 20 are formed along the longitudinal direction of a sanitary napkin 1, on a non-skin contacting surface of an absorber 4, a plurality of horizontally long peripheral embosses 21, 21, ... are formed with spaces in between in the longitudinal direction of the sanitary napkin 1 on the absorber 4 which is located in the vicinity of the concave grooves 20, and an absorber missing part 22 is formed at least between the concave grooves 20, 20 Deformation in the transverse direction of the absorber 4 in the peripheral part is regulated by the peripheral embosses 21, 21, ..., while deformability in the width direction of the napkin can be ensured with the lines of formation of the concave grooves 20, 20 used as flexibility axes, and deformation in directions of compression and tension of the absorber 4 is absorbed by the absorber missing part 22. Therefore, favorable bending is attained along the roundness in the longitudinal direction of the buttocks.COPYRIGHT: (C)2012,JPO&INPIT【課題】臀部の谷間への密着性を向上させ、後漏れを防止する。【解決手段】吸収体4の非肌当接面側に生理用ナプキン1の長手方向に沿って断続的な凹状溝20、20を形成するとともに、前記凹状溝20の周辺に位置する吸収体4に生理用ナプキン1の長手方向に間隔を空けて横長の周辺エンボス21、21…を複数形成され、且つ少なくとも前記凹状溝20、20間に吸収体欠損部22を形成する。周辺エンボス21、21…によって周辺部の吸収体4の横断方向の変形が規制され、前記凹状溝20、20の形成列を可撓軸としてナプキン幅方向の変形性能が確保でき、且つ吸収体欠損部22で吸収体4の圧縮方向や引張方向の変形が吸収されるため臀部の前後方向の丸みに沿って良好に湾曲する。【選択図】図1
