Abstract
A rotating electrical machine includes: a stator that including a stator core and a teeth section, with a stator coil wound at the teeth section; a rotor arranged via a clearance at an inner periphery side of the stator and supported in a freely rotating manner; and a distribution unit supported by a resin holder, and including a conductor connected to the stator coil. The rotating electrical machine is cooled by coolant. The stator coil includes a coil end section projecting from an end of the stator in an axial direction. A gap is formed between an end of the stator core and a lower surface of the distribution unit by mounting the distribution unit on an upper part of the coil end section. The gap constitutes a path for the coolant.
