The present invention relates to an electric booster, preventing damage to components by excessive rotation of a screw part when a brake force is released. The electric booster comprises: a motor part configured to be driven by power applied thereto; a body part mounted and fixed onto the motor part; a cylinder part coupled to the body part; a screw part connected to the motor part and rotated; a nut part embedded in the body part, and screwed to the screw part so as to linearly move; a first piston part constraining an end of the screw part, and moved to the cylinder part while being pressed by the nut part; a first elastic part supporting the first piston part; a second piston part supported by the first elastic part; and a second elastic part supporting the second piston part.
