Abstract:
1. An insulated wire comprising a conductor and an insulation film made of polymer alloy around the conductor, wherein: the polymer alloy consists essentially of an amorphous thermosetting resin and an amorphous thermoplastic resin; the insulation film has a single-layered structure and a sea-island structure and is formed directly on the conductor; the amorphous thermosetting resin is a polyamide-imide resin and is a sea component of the sea-island structure, the sea component is a continuous phase, and the amorphous thermosetting resin has an average molecular mass of 10,000 to 200,000; and the amorphous thermoplastic resin is a polyetherimide resin and is an island component of the sea-island structure, the island component is a dispersed phase, the amorphous thermoplastic resin has an average molecular mass of 15,000 to 200,000, and the island component has an average diameter of less than 1 μm.
