An object of the present invention is to achieve reductions in size and costs of a vehicle-mounted motor driving control board in a configuration which allows the redundancy of a power supply to be ensured. The vehicle-mounted motor driving control board is formed by one printed circuit board on which are formed two inverter driving circuits for driving two inverter circuits for three-phase motors, and a voltage step-up/step-down driving circuit for driving a voltage step-up/step-down circuit for supplying electric power to the inverter circuits. The vehicle-mounted motor driving control board further includes a first power supply circuit for supplying electric power to part of constituent circuits constituting the voltage step-up/step-down driving circuit and the two inverter driving circuits, and a second power supply circuit for supplying electric power to the remainder of the constituent circuits in the voltage step-up/step-down driving circuit and the two inverter driving circuits.
