PROBLEM TO BE SOLVED: To suppress tear of a sheet part laminated on an absorbent body when compressing an absorber.SOLUTION: A production device of an absorbent article comprises: a rotation member 30 having a salient part 31 protruding outward from an outer peripheral face 30E. The salient part 31 has a first side surface part 311S and a second side surface part 312S arranged on a side opposite to a rotation direction B of the rotation member 30 relative to the first side surface part 311S, in a cross section orthogonal to a rotation axis Xof the rotation member 30. A distance L1 of a normal 341NL passing a first intersection 321P between the outer peripheral face 30E and the first side surface part 311S, and a perpendicular 351NL which is drawn from an end point of the first side surface part 311S on a side opposite to the first intersection 321P, to the outer peripheral face 30E, is longer than a distance L2 of a normal 342NL passing a second intersection 322P between the outer peripheral face 30E and the second side surface part 312S, and a perpendicular 352NL which is drawn from an end point of the second side surface part 312S on a side opposite to the second intersection 322P to the outer peripheral face.SELECTED DRAWING: Figure 5【課題】吸収体を圧搾するときに、吸収性本体上に積層されたシート部分が破れることを抑制する。【解決手段】外周面３０Ｅから外方に突出する凸部３１を有する回転部材３０を備え、回転部材３０の回転軸Ｘ30に直交する断面において、凸部３１は、第１側面部３１１Ｓと、第１側面部３１１Ｓより回転部材３０の回転方向Ｂと反対側に位置する第２側面部３１２Ｓと、を備え、外周面３０Ｅと第１側面部３１１Ｓとの第１交点３２１Ｐを通る法線３４１ＮＬと、第１交点３２１Ｐとは反対側にある第１側面部３１１Ｓの端点から外周面３０Ｅに下ろした垂線３５１ＮＬと、の距離Ｌ１は、外周面３０Ｅと第２側面部３１２Ｓとの第２交点３２２Ｐを通る法線３４２ＮＬと、第２交点３２２Ｐとは反対側にある第２側面部３１２Ｓの端点から外周面に下ろした垂線３５２ＮＬと、の距離Ｌ２より長い。【選択図】図５
