  "textContent": "Provided is an electric brake device that is able to achieve redundancy when an abnormality occurs in a load sensor, without increasing the size of the load sensor. The electric brake device includes a brake rotor, a friction pad, an electric motor (2), a transmission mechanism, braking force command section (26a), braking force estimation section (30), motor rotation angle detector (28), and a controller (7). The braking force estimation section (30) includes a load sensor (13) configured to detect elastic deformation of a determined member forming the electric brake device. The controller (7) includes sensor abnormality detector (37) configured to store a sensor output of the load sensor (13) at a motor rotation angle at which a braking force becomes zero, and infer the occurrence of plastic deformation in the load sensor (13) from transition of the stored sensor output.",
