Provided is an in-vehicle power conversion apparatus capable of having the circuit section thereof shielded without using a special shielding member, and capable of achieving low cost and small size. The in-vehicle power conversion apparatus is provided with a conductive housing having an opening, and a multilayer printed wiring board which has the circuit section mounted thereon, and in which one layer thereof is a GND plane. A closed space is formed by assembling the multilayer printed wiring board to the opening plane of the opening of the conductive housing, and the circuit section is shielded by electrically connecting the GND plane of the multilayer printed wiring board to the conductive housing, said circuit section being housed in the closed space surrounded by the conductive housing and the multilayer printed wiring board.
