Abstract
Provided is a winding bobbin with a simple structure, which allows, even when a number of layers formed by winding a conductor is odd, a winding start-side lead wire and a winding end-side lead wire to be led out in the same direction while ensuring a desired outer diameter size of a rotor coil without loosening a tightly wound conductor. The winding bobbin () includes a first flange portion () and a second flange portion () on both sides of a cylindrical winding portion (). The second flange portion () is provided with a second locking portion () for locking a winding end portion () of the conductor which is wound around the winding portion () in an odd number of layers.
