Abstract

PURPOSE:To attempt the reduction of manufacturing processes by using a substance having mold releasability as a heat contractor wound between an insulating layer on a conductor and a metal mold for formation. CONSTITUTION:After winding a heat contractor 3 having mold releasability, for example, a heat contractor composing of fluoride, on an insulating layer 2 coated on a conductor 1, a metal mold 4 is placed on the contractor 3. Next, an insulating coil is formed by pressure formation after winding a heat contractor 5 on the mold 4. In this way, no winding of a mold releasing tape on the insulating layer 2 is needed and manufacturing processes will be reduced by using the contractor 3 having mold releasability.
