Abstract

An insulated wire having a conductor, and a multilayer insulating layer composed of two or more layers coating the conductor, wherein the innermost insulating layer of the multilayer insulating layer is an insulating layer formed of a crystalline thermoplastic resin having a storage elastic modulus of 10 MPa or more at 300° C. and outer insulating layer(s) other than the innermost insulating layer include(s) an insulating layer formed of a crystalline thermoplastic resin having a melting point of 260° C. or higher and a storage elastic modulus of 1,000 MPa or more at 25° C., and adjacent insulating layers have a relationship such that the storage elastic modulus at 25° C. of the thermoplastic resin of the outer insulating layer is equal to or smaller than the inner insulating layer; and electric/electronic equipment formed using the insulated wire as a winding and/or lead wire of a transformer that is incorporated into the electric/electronic equipment.
