Abstract: This brake device (U) comprises: an operation amount detector (31); a wheel speed detector (32); a controller (50) for controlling a wheel brake (F); and an electronic controller (200). The electronic controller (200) sets a target deceleration on the basis of an operation amount of a brake lever (L2), and sets an estimated deceleration on the basis of a wheel speed. Further, the electronic controller (200) controls the controller (50) on the basis of the target deceleration and the estimated deceleration. The brake device (U) improves operation feel for a driver, while being capable of reducing the number of components and simplifying control.
