PROBLEM TO BE SOLVED: To provide a vapor-deposited laminated polyamide resin film which is excellent in oxygen gas-barrier properties, impact resistance, and bending fatigue resistance, prevents the deterioration and discoloration of contents when used as a packaging material and the break of the bag of goods by vibration and impact during transportation, can protect the contents, and is suitable for packaging applications. SOLUTION: In the vapor-deposited laminated polyamide resin film, an inorganic substance is vapor-deposited on at least one side of a biaxially oriented laminated polyamide film produced by laminating a resin layer (B layer) containing an aliphatic polyamide resin as a main component on at least one side of a resin layer (A layer) containing a m-xylilenediamine group-containing polyamide polymer containing m-xylilenediamine or a mixture comprising m-xylilenediamine and p-xylilenediamine as a main diamine component and a 6-12Cα,ω-aliphatic dicarboxylic acid component as a main dicarboxylic acid component as a main component.
