Rectangular wire, and method of producing the same and electrical equipment using the same

A method of producing a rectangular wire comprising:

• a step of forming a multilayer conductor member by stacking, in a thickness direction, a rectangular metallic conductor having formed by bake-coating a layer of a thermosetting resin on the outer periphery thereof, the thermosetting resin having a glass transition temperature of 100° C. or more to 200° C. or less and the thermosetting resin is a thermosetting polyurethane-based resin;
• and a step of coating a layer of a thermoplastic resin having a melting point of 300° C. or more to 450° C. or less only on the outer periphery of the multilayer conductor member, wherein the conductor has a width dimension perpendicular to a stacking direction and misalignment of the width dimension between one conductor to another adjacent conductor in the stacking direction is less than one-third of the width dimension.
