According to the present invention, a wire insulation layer (112) and an interlayer insulation layer (113) are formed on a wire (111). A main insulation layer (114) is formed by winding highly thermally conductive mica tape. A first outer insulation layer (115) formed from heat-shrinking material and a second outer insulation layer (116) formed from a highly thermally conductive resin are formed at a coil end section. Due to this configuration, the thermal conductivity of the coil, particularly of the coil end section, is improved, thereby enabling improved cooling performance. |
