To provide a configuration also considering the impact of magnetic field due to an interconnect line.SOLUTION: A power conversion apparatus includes a first inverter for connection with one end of the wiring of a motor, a second inverter for connection with the other end of the wiring of the motor, a magnetic sensor mounted on a first substrate surface where the first inverter is mounted, and used for controlling the motor, an inverter interconnect line connecting the first and second inverters, a first motor interconnect line connecting the one end and the first inverter, and a second motor interconnect line connecting the other end and the second inverter. The inverter interconnect line has a first location intersecting the first substrate surface, the first motor interconnect line has a second location intersecting the first substrate surface, and the first location is located on the second location side, out of the second location side and the opposite side with the magnetic sensor as the boundary.SELECTED DRAWING: Figure 6
