Claim 0:
1. A rotating electric machine comprising:
a rotor having a columnar rotor core which is fixed to a shaft and generates a magnetic field;
a stator provided so as to surround a circumference of the rotor core, and composed of a stator core and a coil wound through slots of the stator core; and
a frame storing the stator and the rotor, wherein
where a space in which a coil end portion of the coil extending in an axial direction from the stator core is surrounded by the frame and an axial-direction end surface of the stator core is defined as an end housing portion,
the end housing portion is partitioned by a partition plate into a first space on a side where a cooler for cooling a cooling gas circulating in the rotating electric machine is present, and a second space on a side where the coil end portion is present,
the partition plate has, at a radially outer end, an intake port that opens in a circumferential direction,
a shield plate which is a magnetically high-conductive metal plate is provided so as to be connected to a radially inner side from the intake port of the partition plate and arranged along the circumferential direction of the frame, and
a ventilation path is formed between the shield plate and the frame so as to communicate with the intake port.
