Controller for vehicle motor

A controller (100) for a vehicle motor includes a switching unit (12), a capacitor unit (14), output terminals (15a, 15b, 15c) and wiring lines (15d, 15e, 15f). The switching unit (12) is provided on a substrate (11) to control power supply to a motor. The capacitor unit (14) is arranged in the neighborhood of the switching unit (12), and is connected to the switching unit (12). The output terminals (15a, 15b, 15c) are connected to the motor. The wiring lines (15d, 15e, 15f) connect the switching unit (12) and the output terminals (15a, 15b, 15c) in a straight line route.
