Abstract
A stator-core-side expansive additive layer and a coil-side expansive additive layer include foam materials foaming by heating. A foam material included in the stator-core-side expansive additive layer has such a foaming characteristic that an increase characteristic of a foaming rate along with a temperature rise is shifted to a cold side relative to the increase characteristic of a foam material included in the coil-side expansive additive layer.
