Provided is a film laminate which is reduced in the thickness. This film laminate is provided with a PET film, a TAC film that is provided on a first PET surface of the PET film, and an adhesive layer that is provided on a second PET surface of the PET film. If TA is the thickness of the TAC film and TB is the thickness of the PET film, this film laminate satisfies the following conditions 1-4. 20 μm ≤ TA + TB ≤ 100 μm Condition 1 10 μm ≤ TA ≤ 60 μm Condition 2 10 μm ≤ TB ≤ 80 μm Condition 3 0.1 ≤ TB/TA ≤ 3.0 Condition 4 L'invention concerne un stratifié de film qui est réduit en épaisseur. Ce stratifié de film comporte un film de PET, un film de TAC qui est disposé sur une première surface de PET du film de PET, et une couche adhésive qui est disposée sur une seconde surface de PET du film de PET. Si TA est l'épaisseur du film de TAC et TB est l'épaisseur du film de PET, ce stratifié de film satisfait les conditions suivantes 1 à 4. 20 μm ≤ TA + TB ≤ 100 µm Condition 1 10 μm ≤ TA ≤ 60 µm Condition 2 10 μm ≤ TB ≤ 80 μm Condition 3 0,1 ≤ TB/TA ≤ 3,0 Condition 4 厚みを抑えたフィルム積層体を提供する。　フィルム積層体は、ＰＥＴフィルムと、ＰＥＴフィルムの第１ＰＥＴ面に設けられたＴＡＣフィルムと、ＰＥＴフィルムの第２ＰＥＴ面に設けられた粘着層とを備える。ＴＡＣフィルムの厚みをＴＡとし、ＰＥＴフィルムの厚みをＴＢとするときに、フィルム積層体は以下の条件１～４を満たす。　２０μｍ≦ＴＡ＋ＴＢ≦１００μｍ・・・条件１　１０μｍ≦ＴＡ≦６０μ・・・条件２　１０μｍ≦ＴＢ≦８０μｍ・・・条件３　０．１≦ＴＢ／ＴＡ≦３．０・・・条件４
