PROBLEM TO BE SOLVED: To provide a polyamide based laminated biaxially stretched film having excellent oxygen gas barrier properties, excellent bending pinhole resistance and toughness. SOLUTION: The polyamide based laminated biaxially stretched film is a multilayered stretched film containing at least two layers, that is, a layer based on a polyamide resin (X) and a layer (B) comprising a resin Z which contains an aliphatic polyamide resin (Y) and the polyamide resin (X). The polyamide resin (X) is obtained using meta-xylylenediamine and a 6-12Cα,ω-aliphatic dicarboxylic acid as main raw materials and the resin (Z) is based on the aliphatic polyamide resin (Y) and a cut waste material at the time of production of the film is mixed with the aliphatic polyamide resin (Y).
