PROBLEM TO BE SOLVED: To provide a method of continuously peeling a thin film from a base material easily even when the thin film is not flexible and is easy to be broken.SOLUTION: A support body 3 is overlapped with a thin film 2 so that the thin film 2 is exposed to an outside than a pair of both opposite end parts 7 of the support body 3 in a state that the support body 3 is overlapped with the thin film 2 formed on a surface of a base material 1. An adhesive tape 4 is stuck on both end parts 7 of the support body 3 and the thin film 2 so as to bridge each of the end parts of both end parts 7 of the support body 3 and a part of the thin film 2 exposed to the outside than the end parts. One end part except for both end parts 7 of the support body 3 is pulled up, and the support body 3 is separated from the base material 1 so as to peel from a side of the pulled end part in a state that both end parts 7 of the support body 3 and the thin film 2 are stuck by the adhesive tape 4 to peel the thin film 2 together with the support body 3 from the base material 1.SELECTED DRAWING: Figure 3 【課題】柔軟性がなく破れやすい薄膜であっても、簡便にベース基材から薄膜を連続的に剥離する方法の提供。【解決手段】ベース基材１の面に形成された薄膜２に支持体３が薄膜に重ねられた状態で、支持体３の対向する一対の両端部７よりも外側に薄膜２が露出するように、支持体３を薄膜２に重ねる工程と、支持体３の両端部７のそれぞれの端部と、その端部より外側に露出している薄膜２の部分とにまたがるように、粘着テープ４を支持体３の両端部７と薄膜２とに貼り付け、支持体３の両端部７以外の１箇所の端部を引き起こし、粘着テープ４により支持体３の両端部７と薄膜２とが貼り付けられた状態のまま、前記引き起こした端部の側から剥がすようにして支持体３をベース基材１から離していくことで、支持体３と共に薄膜２をベース基材１から剥離する方法。【選択図】図３
