Abstract
Provided is a motor bobbin around which a winding wire is wound, said motor bobbin comprising insulating paper and a resin molded body. The insulating paper and the resin molded body are coupled and fixed together without using an adhesive agent. Surfaces of the insulating paper which are in contact with the resin molded body are configured using aramid paper comprising an aramid fibrid and aramid short fibers. Resin is melt extruded and thermal-fusion bonded upon the aramid paper comprising the aramid fibrid and the aramid short fibers, and the surfaces configured from the aramid paper are surface treated to obtain the insulating paper. The motor bobbin is obtained by bringing melted portions of the resin molded body into contact with the top of the aramid paper.
