Summary:To provide a new protective film having an inorganic layer provided on one surface side of a base material film, which can obtain higher gas barrier property and a method for producing the same, and a film laminate using the protective film.SOLUTION: A protective film has such a structure that an inorganic layer and a crosslinked resin layer are layered in this order on one surface side of a base material film (1), in which the crosslinked resin layer contains alkali earth metal ions or alkali metal ions.SELECTED DRAWING: None 【課題】基材フィルムの片面側に無機物層を備えた保護フィルムに関し、より高いガスバリア性を得ることができる新たな保護フィルム及びその製造方法、さらには、該保護フィルムを用いたフィルム積層体を提供する。【解決手段】基材フィルム（１）の片面側に、無機物層及び架橋樹脂層がこの順に積層してなる構成を備えた保護フィルムであって、前記架橋樹脂層がアルカリ土類金属イオンまたはアルカリ金属イオンを含む保護フィルムである。【選択図】なし
