Abstract

PURPOSE:To prevent a void from occurring by inserting a wave-shaped insulator with designated wave height between conductors, and performing resin molding. CONSTITUTION:Wave-shaped insulators 5 with designated wave height are inserted into a conductor 1, taking proper intervals in the proceeding direction of wave, while the conductor 1 is being wound. A coil with equal intervals between layers of the conductor 1 is formed by thus winding the conductor 1. Next, this coil is arranged in a designated metal mold, a thermosetting resin 3 is injected, and heat hardening process is carried out. As a thus-obtained injected coil is formed in a wave-shaped insulator, the resin 3 enters into every part of the conductor 1 and a void is prevented from occurring. In addition, even if a long wave-shaped insulator 5, superposed with a conductor 1, is wound at the same time, the same effect will be expected.
