PROBLEM TO BE SOLVED: To provide a heat-resistant voice coil having coil shaped holding capability under a high temperature of 200°C to 250°C by providing various electrical appliance coils whose bonding by alcohol is possible, and whose heat resistivity is required, especially, heat-resistant self-fusing wires suitable for manufacturing a voice coil. SOLUTION: Silane modified epoxide resin 50 to 70 weight portions to which alkoxy silane has been position-selectively and chemically bonded is added to refractory alcoholic solubility polyamide resin 80 to 100 weight portions whose melting points are ranging 155°C or more to 200°C or less while the epoxy group of epoxy resin is left, and heat-resistant fusing paint obtained by dissolving this in organic solvent is directly or through the other insulating coating (2) applied and burnt on a conductor (1), and an alcoholic solubility fusing coating (3) having heat resistivity is formed so that a heat-resistant self-fusing wire (5) can be configured.
