1. An electric brake, comprising:
a brake mechanism configured to transmit a thrust force generated through drive of an electric motor to a piston, the piston being configured to move brake pads to be pressed against a disc;
a thrust force detection unit configured to detect the thrust force transmitted to the piston; and
a control device configured to control the drive of the electric motor based on a detection value obtained by the thrust force detection unit,
wherein the control device is configured to set, as a reference point of a piston thrust force, a detection value obtained by the thrust force detection unit when the electric motor is driven to move the piston toward a direction for pressing the disc in a range in which the brake pads are not in contact with the disc.
