PROBLEM TO BE SOLVED: To provide a glass film laminate which allows easy peeling of a glass film from a support glass while preventing damage of the support glass in a production-related treatment and damage of a glass film during peeling of the glass film from the support glass.SOLUTION: A glass film laminate 1 consists of a support glass 3 and a glass film 2, laminated with their mating surfaces surface-contacted. The glass film 2 is not protruded from the support glass 3. In the vicinity of an end side 32 of the support glass 3, a protrusion part 31 protruding toward the glass film 2 side is provided, and the glass film 2 is in contact with the protrusion part 31. In the vicinity of an end side 21 of the glass film 2, there is provided a peeling region 11 which is surrounded by the support glass 3, the protrusion part 31 and the glass film 2 and holds both mating surfaces of the support glass 3 and the glass film 2 in a non-contact state. A method of peeling a glass film comprises peeling the glass film 2 from the support glass 3 by expanding the peeling region 11. 【課題】製造関連処理時の支持ガラスの破損や、支持ガラスからガラスフィルムを剥離する際のガラスフィルムの破損を防止しつつ、支持ガラスからガラスフィルムを容易に剥離可能とするガラスフィルム積層体。【解決手段】支持ガラス３とガラスフィルム２とを、それぞれの合わせ面を面接触させて積層したガラスフィルム積層体１であって、ガラスフィルム２は支持ガラス３から食み出しておらず、支持ガラス３の端辺３２近傍には、ガラスフィルム２側に突出する突出部３１が設けられ、ガラスフィルム２は、突出部３１と接触しており、ガラスフィルム２の端辺２１近傍には、支持ガラス３と突出部３１とガラスフィルム２とで囲繞され且つ支持ガラス３とガラスフィルム２との両合わせ面が非接触状態とされた剥離領域１１が設けられているガラスフィルム積層体。剥離領域１１を広げていくことで、支持ガラス３からガラスフィルム２を剥離するガラスフィルムの剥離方法。【選択図】図１
