An electric booster including a plunger movable by operation of a brake pedal, an electric motor controlled based on a relative displacement between the plunger and the linear motion member, which is detected by a relative displacement sensor, and a ball and screw mechanism. The linear motion member pushes a piston of a master cylinder through a reaction member, thereby generating a brake force. Part of a reaction force from the master cylinder is fed back to the brake pedal through the reaction member. When a reference position sensor detects that a relative position of the plunger to the linear motion member coincides with a predetermined reference position, a detection value of the relative displacement sensor is stored as a relative displacement reference value, and relative displacement between the plunger and the linear motion member is determined.
