In a multilayer printed circuit board (circuit board 20) having an inverter (switching elements 22) mounted thereto, only a second wiring pattern P2 arranged downstream of a semiconductor relays 24 and able to shut off an electric power supply and a third wiring pattern P3 arranged upstream of a shunt resistor 27 and able to detect an overcurrent are placed in adjacent layers in a manner to face each other, and thus, even if the mutually facing portions (laminated portion) of the these two wiring patterns P2 and P3 are subjected to short circuit, an overcurrent caused by the short circuit can be detected by the shunt resistor 27 and the electric power supply to the switching elements 22 can be shut off by the switching elements 22, so that overheating at the second and third wiring patterns P2 and P3 can be avoided.
