PROBLEM TO BE SOLVED: To provide a polyamide multilayer film excellent in bending related pinhole resistance and barrier properties and having a glossy appearance. SOLUTION: The polyamide multilayer film is composed by laminating a polyamide layer [layer (A)], an oxygen barrier layer [layer (B)] and a polyamide layer [layer (C)] in this order; wherein the layer (A) contains an aliphatic polyamide, the layer (B) contains 55-95 wt.% of a saponified ethylene-vinyl acetate copolymer and 5-45 wt.% of an elastic polymer and the layer (C) contains an aliphatic polyamide.
