INSULATED WIRE AND ELECTRIC OR ELECTRONIC EQUIPMENT

摘要

An insulated wire that comprises a multilayer insulating layer which is composed of two or more layers and which covers a conductor. The innermost insulating layer of the multilayer insulating layer is formed of a crystalline thermoplastic resin that has a storage modulus at 300°C of 10 MPa or more, and the outer insulating layer(s) other than the innermost insulating layer contain(s) an insulating layer that is formed of a crystalline thermoplastic resin that has a melting point of 260°C or more and a storage modulus at 25°C of 1,000 MPa or more. With respect to two adjacent insulating layers of this insulated wire, the storage modulus at 25°C of the thermoplastic resin of the outer insulating layer is equal to or smaller than that of the inner insulating layer. An electrical/electronic device which uses this insulated wire as a winding wire and/or a lead wire of a transformer that is incorporated in the electrical/electronic device.
