The electric brake device includes a control device for performing follow-up control such that a braking force estimated value estimated by a braking force estimator follows a given braking force command value. The control device includes an angle-sensorless control function section for determining a phase of phase current of an electric motor irrespective of an actual angle of the electric motor and controlling the electric motor to have a current value that is based on the determined phase of the phase current. The angle-sensorless control function section includes a current phase determination section for determining a current phase that is the phase of the phase current of the electric motor on the basis of a deviation between the braking force command value and the braking force estimated value.
