AUXILIARY NAPKIN AND NAPKIN SET

To provide an auxiliary napkin which is easily attached/detached to/from a sanitary napkin.SOLUTION: There is provided an auxiliary napkin (1) which is used by being attached to a skin side face of a sanitary napkin (2). A non-skin side face of the auxiliary napkin (1) is provided with an attachment part (31). A non-skin side face of the sanitary napkin (2) is provided with an adhesive part (41). An average value of the magnitude of the force that is applied when peeling the auxiliary napkin (1) from a second auxiliary napkin (1B) along the longitudinal direction after attaching the entire region of the attachment part (31) in the unused state to the skin side face of the second auxiliary napkin (1B) is smaller than an average value of the magnitude of the force that is applied when peeling the sanitary napkin (2) from the second sanitary napkin (1B) along the longitudinal direction after attaching the entire region in the width direction and the 50 mm region in the longitudinal direction of the adhesive part (41) in the unused state to the skin side face of the second auxiliary napkin (1B).SELECTED DRAWING: Figure 5 【課題】生理用ナプキンに対して着脱が容易な補助ナプキンを提供する。【解決手段】生理用ナプキン（２）の肌側面に取り付けて使用される補助ナプキン（１）であって、補助ナプキン（１）の非肌側面には取り付け部（３１）が設けられており、生理用ナプキン（２）の非肌側面には粘着部（４１）が設けられており、未使用状態の取り付け部（３１）の全領域を、第２補助ナプキン（１Ｂ）の肌側面に取り付けてから、長手方向に沿って第２補助ナプキン（１Ｂ）から補助ナプキン（１）を剥がすときにかかる力の大きさの平均値は、未使用状態の粘着部（４１）のうち、幅方向における全体及び長手方向における５０ｍｍの領域を、第２補助ナプキン（１Ｂ）の肌側面に貼付してから、長手方向に沿って第２補助ナプキン（１Ｂ）から生理用ナプキン（２）を剥がすときにかかる力の大きさの平均値よりも小さい。【選択図】図５
