A stretched polyamide film including at least one stretched layer made of a mixed resin containing a polyamide resin X and a modified polyester-based elastomer Y. The polyamide resin X is mainly constituted by m-xylylenediamine unit and C<6-12> alpha, omega-aliphatic dicarboxylic acid unit. The modified polyester-based elastomer is graft-modified with an ethylenically unsaturated carboxylic acid or its anhydride. Such stretched polyamide film is drastically improved in the flexibility, impact resistance and pin-hole resistance with little reduction in the gas-barrier properties while retaining an enough transparency to practical use.
