Abstract
A rotating electric machine includes a stator core, a stator coil formed of electrical conductors and insulating coats respectively covering the electrical conductors, and an encapsulating resin body. The stator coil has a coil end part protruding from the stator core. The coil end part includes exposed portions of the electrical conductors, which are exposed from the insulating coats, joints formed at the exposed portions, and covered portions of the electrical conductors which are covered with the respective insulating coats and respectively adjoin the exposed portions. The encapsulating resin body has a first part in which the exposed portions of the electrical conductors and the joints are encapsulated, and a second part in which at least part of each of the covered portions of the electrical conductors is encapsulated. A coefficient of linear expansion of the first part is lower than a coefficient of linear expansion of the second part.
