The electric power steering device includes a motor and a control unit integrated coaxially therewith at an output shaft end of the motor. The motor has two sets of windings independently of each other. The control unit includes two inverter circuits having a plurality of switching elements for supplying currents, and two control circuits for respectively outputting drive signals to the inverter circuits. The inverter circuits are formed by power modules, and have detection terminals for detecting voltages between both ends of shunt resistors for detecting currents. Shield walls for shielding noise are provided to a heatsink for supporting the power modules and control boards forming the control circuits. The shield walls support the control boards.
