An end housing portion of a rotating electric machine is partitioned by a partition plate into a first space on the side where a cooling cooler is present and a second space on the side where a coil end portion is present. The partition plate has, at a radially outer end, an intake port that opens in the circumferential direction. A shield plate which is a magnetically high-conductive metal plate is provided so as to be connected to the radially inner side from the intake port of the partition plate and arranged along the circumferential direction of the frame. A ventilation path D is formed between the shield plate and the frame so as to communicate with the intake port.
