PROBLEM TO BE SOLVED: To provide a biaxially-oriented laminated polyamide film which is excellent in oxygen gas-barrier properties, impact resistance, and bending fatigue resistance and has a good thickness spot. SOLUTION: The biaxially-oriented laminated polyamide film is composed, which fills up a specified small thickness spot range formed by laminating a resin layer (layer B) containing an aliphatic polyamide resin as a main component on at least one side of a resin layer (layer A) mainly containing a m-xylilene group-containing polyamide polymer containing m-xylilene diamine or mixed xylilene diamines comprising m-xylilene diamine and p-xylilene diamine as a main diamine component and a 6-12Cα,ω-aliphatic dicarboxylic acid component as a main dicarboxylic acid component, a pinhole number range, an oxygen transmittance range, and a specified large peel strength range.
