An electric brake device (34) to be mounted on a vehicle includes a rotating body, a friction member (126), an electric motor (18), a piston (42a; 86; 142), an operation conversion mechanism (150), an actuator (110), and a controller. The operation conversion mechanism (150) is configured to include a rotating member and a linear motion member. The controller is configured to selectively execute (a) a standby control of causing the linear motion member to stand by at a standby position where a clearance between the friction member (126) and the rotating body is not larger than a backlash between a male screw and a female screw, and (b) a backward movement control of moving the linear motion member backward to a backward movement position where the clearance is allowed to be equal to or more than the backlash, in a case where there is no braking force request for the electric brake device (34).
