PROBLEM TO BE SOLVED: To provide a division label having machine adaptability for accurately guiding a cutting direction in the case of separating and peeling a division part from a body part to a perforation cutting direction and medical drug to which this division label is attached.SOLUTION: There is disclosed the division label configured such that a body part and a division part are connected so as to be separated via a perforation, and that the division part is formed so as to be reused, in which the perforation is composed of Y-shaped cuts each of which has a main cut part, a division part side cut part, and a body part side cut part. The shape and layout relation of each Y-shaped cut is determined such that, concerning a top end A of the main cut part in the preceding-order Y-shaped cut and a notch intersection O, a top end B of the division part side cut part, and a top end C of the body part side cut part in the following-order Y-shaped cut, a division part side displacement allowable angle ∠BAO is ranging from 60 to 90°, and a body part side displacement allowable angle ∠CAO is ranging from 25 to 90°. There is disclosed medical drug to which this division label is attached.COPYRIGHT: (C)2013,JPO&INPIT【課題】分割部を本体部から切り離して剥離させる際の切断方向を確実にミシン目切断方向に案内することができ、しかも、機械適合性をも有する分割ラベル、及びこの分割ラベルが付された医薬品製剤を提供する。【解決手段】本体部と分割部とがミシン目を介して切離し可能に接続され、分割部が再利用可能な分割ラベルであって、ミシン目が主カット部、分割部側カット部、及び本体部側カット部を有するY字カットであり、また、各Y字カットの形状及び配置関係が、前位のY字カットと後位のY字カットにおいて、前位のY字カットにおける主カット部の先端Aと、後位のY字カットおける切込交点O、分割部側カット部の先端B、及び本体部側カット部の先端Cに関し、分割部側ズレ許容角度∠BAOが60~90°の範囲内であって、本体部側ズレ許容角度∠CAOが25~90°の範囲内である分割ラベルであり、また、この分割ラベルが付された医薬品製剤である。【選択図】図2
