In an electric driving apparatus, a sensor magnet is fixed to a first end portion of a rotary shaft of a motor. A sensor device includes a rotation sensor that detects a magnetic field generated by the sensor magnet. The rotation sensor opposes the sensor magnet in an axial direction of the rotary shaft. A control unit mounted on the motor includes an inverter circuit that is connected to an armature winding of the motor via a plurality of feeder wires. The inverter circuit is disposed in a position further from the sensor magnet than the rotation sensor in the axial direction of the rotary shaft. A shield plate formed from a magnetic material is disposed between the rotation sensor and the inverter circuit.
