PURPOSE:To suppress a partial discharge which is generated between the insulating surfaces of the coil pieces of a laminated core by forming a semiconductive layer at an adjacent interval by winding a tape on the linear part of a hexagonal coil piece. CONSTITUTION:A main insulating layer 103 is formed in a hexagonal guide 104, thereby forming a hexagonal coil piece 1, and a semiconductive tape 2 is wound at an adjacent interval on a linear part 101 of the piece 1, thereby forming a semiconductive layer 2A. In this manner, the winding work can be facilitated, the working time can be shortened, and resin can be readily impregnated in a main insulating layer 103. |
