An electric brake apparatus includes an electric motor including a plurality of driving circuits, an electric mechanism configured to press a braking member against a braking target member based on driving of the electric motor, and a control device configured to control the driving of the electric motor. The control device detects contact between the braking member and the braking target member based on a change in a current of the electric motor when power is supplied to a part of the driving circuits among the plurality of driving circuits. More specifically, the change amount of the current between before and after the braking member and the braking target member contact each other is larger when power is supplied to a part of the driving circuit than when power is supplied to all of the plurality of driving circuits.
