Abstract

A vehicle drive device includes: a rotary electric machine including a rotor and a stator; a housing member forming a housing chamber that houses the rotary electric machine; a cover member connected to one end side of the housing member in an axial direction, facing the rotary electric machine in the axial direction, and including a support portion that rotatably supports the rotor; a power switching element electrically connected to a coil of the stator; and a smoothing capacitor electrically connected to the power switching element. The power switching element and the smoothing capacitor are fixed to the cover member and disposed between the cover member and the rotary electric machine in the axial direction. The smoothing capacitor overlaps the power switching element when viewed in a radial direction.
