Abstract
The thermoplastic resin composition includes a polyphenylene ether resin, and the deflection temperature under load of the thermoplastic resin composition is 120° C. or higher, and when a temperature range while the thermoplastic resin composition is heated from −30° C. to 120° C. is divided into temperature ranges with intervals of 10° C., and a low temperature side and a high temperature side of respective two adjacent temperature ranges are defined as a low temperature range and a high temperature range, respectively, a low temperature range expansion coefficient of the resin composition in a TD direction (mm/mm/° C.) and a high temperature range expansion coefficient of the resin composition in the TD direction (mm/mm/° C.) satisfy the following relationship in any of the two adjacent temperature ranges: −50≤((high temperature range expansion coefficient−low temperature range expansion coefficient)/low temperature range expansion coefficient)×100≤50.
