A power control unit is mounted on a vehicle, and controls the electric power for vehicle-running. The power control unit includes: a PCU case (50) having a lid (51) where an opening (53) is formed; a terminal block (61) having a connector retain hole (110) for retaining an interlock connector (120) formed, and arranged at the PCU case (50), facing the opening (53); and a substrate (70) stored in the PCU case (50), and on which an electronic component (84) is mounted. The substrate (70) is arranged at the side opposite to the lid (51) relative to the terminal block (61), and deviated from the position facing an aperture of the connector retain hole (110). The power control unit includes a wall (130) provided integrally with the terminal block (61), and arranged between the substrate (70) and the connector retain hole (110). By such a configuration, there is provided a power control unit having an intrusion of a foreign object suppressed while aiming to reduce the size and cost. |
