ELECTRIC BRAKE DEVICE

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 (2); a brake rotor (5); a friction pad (6); a linear motion mechanism (4); a braking force command section (26a); a braking force estimation section (30); a motor rotation angle detector (28); and a controller (7). The controller (7) is provided with a pad wear amount estimation section (37) configured to estimate a wear amount of the friction pad (6) at a present time by comparing a correlation between the motor rotation angle detected by the motor rotation angle detector (28) and the braking force obtained by the braking force estimation section (30) with a defined correlation between a motor rotation angle and a braking force when the friction pad (6) is unworn.
