PROBLEM TO BE SOLVED: To provide a motor bobbin which may be immune to efficiency improvement/output enlargement of a motor generator or the like.SOLUTION: A motor bobbin 1 around which a winding is wound is formed from insulation paper and a resin molding. In the motor bobbin 1, the insulation paper and the resin molding are concatenated and fixed without using an adhesive agent. A surface of the insulation paper abutted with the resin molding is formed from aramid paper comprised of aramid fibrid and aramid short fiber. The insulation paper is obtained by fusing, extruding and heat-depositing a resin onto the aramid paper formed from the aramid fibrid and the aramid short fiber, and performing surface processing on a surface formed from the aramid paper. A fused portion of the resin molding is brought into contact onto the aramid paper. |
