A brake device (10, 30) using an electric actuator (11, 31) as a drive source is configured to detect a wear amount of a frictional member (14, 34A, 34B).A brake device (10, 30) applies a brake to a vehicle provided with a wheel (2) by controlling a motor (11) to drive a frictional member (14, 34A, 34B), and the frictional member (14, 34A, 34B) is pressed against a target member (2, 3), which is the wheel (2) or a rotating body rotatable integrally with the wheel (2). The brake device (10, 30) includes an acquiring unit (22) for acquiring driving information regarding driving of the motor (11), a travel distance calculating unit (23) for, based on the acquired driving information, calculating a travel distance by which a brake block (14) travels to touch a tread surface (2A) of the wheel (2), and a wear amount calculating unit (24) for calculating a wear amount of the brake block (14) based on a currently calculated value of the travel distance and an old value of the travel distance.
