A polyamide film laminate, comprising
- A) a first polyamide resin layer comprising an amide bond by an aromatic diamino group and a benzene-dicarbonyl group,
- wherein the benzene dicarbonyl group comprises a benzene-1,3-dicarbonyl group and a benzene-1,4-dicarbonyl group,
- wherein a ratio of the benzene-1,3-dicarbonyl group to a total of the benzene-1,3-dicarbonyl group and the benzene-1,4-dicarbonyl group in the first polyamide resin layer is 2 mol % to 8.8 mol %, and
- B) a second polyamide resin layer formed on at least one surface of the first polyamide resin layer and comprising an amide bond by an aromatic diamino group and a benzene-dicarbonyl group,
- wherein the benzene dicarbonyl group comprises a benzene-1,3-dicarbonyl group and a benzene-1,4-dicarbonyl group,
- wherein a ratio of the benzene-1,3-dicarbonyl group to a total of the benzene-1,3-dicarbonyl group and the benzene-1,4-dicarbonyl group in the second polyamide resin layer is more than 20 mol % and 40 mol % or less.
