When a case of a rotary electric machine has an inner case member that houses a stator and an outer case member that houses the inner case member, a vibration that is transmitted from stator to the outer case member via inner case member is suppressed. The inner case portion is provided with a first tubular portion and a first protruding portion that protrudes toward a radial inner side from the first tubular portion on an axial first side. The outer case portion is provided with a second tubular portion and a second protruding portion that protrudes toward the radial inner side from the second tubular portion on the axial first side with respect to the first protruding portion. A coolant flow path is formed between the first tubular portion and the second tubular portion, and the first protruding portion and the second protruding portion are fixed to each other.
