Claims (2)

少なくとも片面側に第１セパレータを有する粘着体を、打ち抜き加工して所定形状の光学用粘着シートを製造する方法において、
前記打ち抜き加工は、前記第１セパレータを前記粘着体から剥離した後、該粘着体に第２セパレータを貼り直して、前記粘着体と前記第２セパレータとの間の剥離力が低い状態で行うことを特徴とする、光学用粘着シートの製造方法。 In the method for producing an optical pressure-sensitive adhesive sheet having a predetermined shape by punching an adhesive body having a first separator on at least one side,
The punching process is performed in a state where the first separator is peeled off from the adhesive body, the second separator is reattached to the adhesive body, and the peeling force between the adhesive body and the second separator is low. A method for producing an optical pressure-sensitive adhesive sheet. 前記剥離力が、該粘着体と前記第１セパレータとの間の剥離力に対し、剥離角度０°で測定して、少なくとも１０％以上低いことを特徴とする、請求項１に記載の光学用粘着シートの製造方法。   2. The optical device according to claim 1, wherein the peeling force is at least 10% lower than the peeling force between the pressure-sensitive adhesive body and the first separator as measured at a peeling angle of 0 °. A method for producing an adhesive sheet.
