摘要： A multilayer insulated wire has two or more extrusion-coating insulating layers provided on a conductor directly or via some other layer, or provided on the outside of a multicore wire composed of conductor cores or insulated cores that are collected together, wherein at least one of the insulating layers is made of a mixture prepared by mixing 100 parts by weight of a polyethersulfone resin and 10 to 100 parts by weight of an inorganic filler. A transformer utilizes the multilayer insulated wire. The multilayer insulated wire can realize such high heat resistance as heat resistance F class (155° C.), which satisfies IEC 950 standards, or higher heat resistance, in transformers; and can exhibit excellent electrical properties even at high frequencies. Further, when the transformer is used at high frequencies, the electric properties are not lowered, and influence by the generation of heat can be prevented.
