Abstract
A rotary electric machine in which a capacitor does not explode even if heat is generated in the capacitor, is provided. A heat sink includes a recess-shaped capacitor housing portion having an inner peripheral side surface joined to an outer peripheral side surface of a capacitor via a capacitor heat dissipation material, and the capacitor housing portion includes an explosion-proof valve recess located at a position facing an explosion-proof valve of the capacitor, and a communication passage providing communication between a drive circuit board and the explosion-proof valve.
