Abstract

A resin film for laminating a metal plate including a resin composition including a polyester-based thermoplastic elastomer and a thermoplastic polyester having a glass transition temperature (Tg) of 70° C. or more and 90° C. or less. The thermoplastic elastomer is dispersed in the thermoplastic polyester. A content of the thermoplastic elastomer in the film is 2 to 50 wt %, and an absolute value ΔTg of a difference between a glass transition temperature of the thermoplastic polyester and a glass transition temperature of the film satisfies the following Expression (1):ΔTg<0.5×W (1)wherein W represents the thermoplastic elastomer content (wt %) in the film.
