The electric brake device includes an electric motor, a friction pad, a linear motion mechanism, a braking force command section, a braking force estimation section, and a controller. The controller is provided with a pad wear amount estimation section to estimate a wear amount of the friction pad and a motor rotation angle detector to detect a motor rotation angle. The pad wear amount estimation section estimates a wear amount of the friction pad from the rotation angle of the electric motor, obtained by the motor rotation angle detector, which rotation angle corresponds to a distance between a retraction end at which a linear motion portion of the linear motion mechanism is separated from a brake rotor and an advance end at which the linear motion portion approaching the brake rotor generates the braking force.
