Abstract: A gas barrier film includes a base material containing a polyethylene as a main resin component and an inorganic oxide layer or an oxygen barrier membrane formed on a first surface side of the base material. The probe descent temperature of the base material on the first surface side is 180° C. or lower, and the proportion of the polyethylene in the entire gas barrier film is 90 mass % or more.
