PROBLEM TO BE SOLVED: To provide a laminated polyamide film which is less yellowish and has good film appearance, high water vapor permeability, smoking treatment effect and elution resistance, and slidability. SOLUTION: The laminated polyamide film includes at least two layers: an (a) layer made of (A1) polyamide resin composition containing 80- 98 mass% of (A) polyamide resin and 2-20 mass% of (B) vinyl amide polymer, and a (b) layer made of (A2) polyamide resin composition containing 70-98 mass% of (A) polyamide resin and (C) 2-30 mass% of poly (N- vinyl lactam) cross-linked body. The (b) layer made of (A2) polyamide resin composition is arranged on a foodstuff contact surface, and the (a) layer made of the (A1) polyamide resin composition is arranged on a side opposite the foodstuff contact surface with respect to the (b) layer.
