A rotating electric machine includes a ring-shaped cover. The ring-shaped cover includes an outer peripheral portion, an inner peripheral portion, wall portions, an outer peripheral channel, an inner peripheral channel, and radial channels. A coolant supplied into the ring-shaped cover is to flow through the outer peripheral channel by gravity. The coolant is to flow through the inner peripheral channel by gravity. The radical channels include a first radial channel and a second radial channel. The coolant is to flow from the outer peripheral channel to the inner peripheral channel by gravity through the first radial channel. The coolant is to flow from the inner peripheral channel to the outer peripheral channel by gravity through the second radial channel. The coolant is to flow from the second radical channel by gravity through the outer peripheral channel.
