PROBLEM TO BE SOLVED: To improve the adhesion of an inorganic oxide layer to a substrate film made of a polyamide resin. SOLUTION: A transparent polyamide film 110 includes: a substrate film 111 made of the polyamide resin; and an easy adhesion layer 112 obtained by applying plasma treatment to a resin layer formed on the substrate film by using a mixture containing a water-dispersible polyester polyurethane and/or a water-dispersible polyester polyurethane polyurea resin and bisphenol glycidyl ether. The ratio D<SP>*</SP>/D<SP>0</SP>between the mole ratio D<SP>*</SP>of a urethane linkage to the C-C linkage of the surface of the easy adhesion layer 112 after the application of the plasma treatment and the mole ratio D<SP>0</SP>of the urethane linkage to the C-C linkage of the surface of the resin layer before the application of the plasma treatment is larger than 0.75 and smaller than 0.97.
