Abstract
An in-vehicle power conversion device includes a drive unit, a casing and a plurality of busbars. The drive unit converts and transmits electric power. The casing includes electrical input-output parts and a main body. The main body includes a housing portion that houses the drive unit, and a lid body that closes the housing portion. The busbars electrically connect the drive unit and the electrical input-output parts of the casing to and from which electric power is inputted and outputted. The electrical input-output parts are routed outside of the casing. The busbars have heat-dissipating portions that are arranged along the casing to transfer heat to the casing outside of the housing portion.
