Insulated wire

An inverter surge-resistant insulated wire, having at least one enamel baked layer around the outer periphery of a conductor, and at least one extrusion-coated resin layer on the outer side thereof, and having an adhesive layer between the enamel baked layer and the extrusion-coated resin layer, thereby the wire is reinforced in adhesive force between the enamel baked layer and the extrusion-coated resin layer, with the adhesive layer as a medium,

• wherein the sum of the thickness of the enamel baked layer, the extrusion-coated resin layer, and the adhesive layer is 60 μm or more,
• wherein the thickness of the enamel baked layer is 50 μm or less, and
• wherein the extrusion-coated resin layer is formed from a polyphenylene sulfide resin composition, which contains a polyphenylene sulfide polymer having a melt viscosity at 300° C. of 100 Pa·s or more, 2 to 8 mass % of a thermoplastic elastomer, and an antioxidant, and which has a tensile modulus of elasticity at 25° C. of 2,500 MPa or more, and a tensile modulus of elasticity at 250° C. of 10 MPa or more.
