Zusammenfassung:	A braking control device drives an electric motor based on a command pressing force corresponding to the required wheel braking force, and presses a friction member against a rotation member fixed to the wheel to generate a wheel braking force. The braking control device includes: a sensor for detecting wheel speed; a sensor for detecting the actual pressing force applied by the friction member; and a controller for calculating the target pressing force based on the command pressing force, and controlling the motor so that the target and actual pressing forces match. The controller calculates wheel slip state quantity based on the wheel speed, and executes, based on the slip state quantity, slip suppression control for reducing the degree of wheel slippage. Based on the actual pressing force at the start of the slip suppression control, the controller reduces the command pressing force and calculates the target pressing force.
