Provided is an electric brake device that can prevent a pad wear from progressing beyond its limit, and can estimate the wear of the friction pad without an increase in cost and space. The electric brake device includes: an electric motor; a brake rotor; a friction pad; a linear motion mechanism; a braking force command section; a braking force estimation section; a motor rotation angle detector; and a controller. The controller is provided with a pad wear amount estimation section configured to estimate a wear amount of the friction pad at a present time by comparing a correlation between the motor rotation angle detected by the motor rotation angle detector and the braking force obtained by the braking force estimation section with a defined correlation between a motor rotation angle and a braking force when the friction pad is unworn.
