PURPOSE:To provide a small-sized molded coil, whose dielectric breakdown strength is improved. CONSTITUTION:A bare conductor 14 and an elastomer 15 are simultaneously wound to form a winding body 13. At this time, as the elastomer 15 has an elasticity, it is deformed as it is wound and is brought in a state that it is closely adhered to the conductor 14 in such a way as to encircle the conductor 14. Subsequently, when the conductor 14 is molded with an epoxy resin 18, the conductor 14 is further closely adhered to the resin 18 because the elastomer 15 has a thermoplasticity and at the same time, fine void parts between the conductor 14 and the elastomer 15 are filled. Thereby, a molded coil 11, whose dielectric breakdown strength is improved, can be obtained. |
