The purpose of the present invention is to provide a gas barrier film which has high gas barrier properties and excellent repeated reproducibility of the gas barrier properties. A gas barrier film which is obtained by sequentially laminating layer (A) and layer (B) described below on at least one surface of a polymer base. Layer (A): a crosslinked resin layer having a pencil hardness of H or more and a surface free energy of 45 mN/m or less Layer (B): a silicon-containing inorganic layer having a thickness of 10-1000 nm
