PROBLEM TO BE SOLVED: To provide a coil for a sealed type drive motor suppressing a breakdown or the like at a high temperature and having an excellent reliability. SOLUTION: In the coil for the sealed type drive motor, a thermosetting-resin composition is subjected to vacuum-pressure impregnating treatment to a winding body winding an insulating tape on the outer periphery of a coil wire. In the coil for the sealed type drive motor, the thermosetting-resin composition contains (a) a dimaleimide compound, (b) an epoxy resin, (c) an isocyanuric-acid derivative having at least one functional group having an unsaturated bond and (d) an acid anhydride as essential ingredients. In the coil for the sealed type drive motor, a heating loss in 24-hour treatment at 300°C after curing is 10% or less in the thermosetting-resin composition. COPYRIGHT: (C)2009,JPO&INPIT
