PROBLEM TO BE SOLVED: To solve the problem that it is difficult to control the hydraulic pressure of a wheel cylinder based on the supplied fluid amount and discharged fluid amount of the wheel cylinder by operation characteristics representing a relationship between the supplied fluid amount to the wheel cylinder and the hydraulic pressure of the wheel cylinder. SOLUTION: In the brake control device imparting braking force to a wheel by a hydraulic pressure applied to the wheel cylinder by supplying a brake fluid to the wheel cylinder through a hydraulic pressure circuit, a hydraulic pressure source is provided in the hydraulic pressure circuit and applies the hydraulic pressure to the wheel cylinder according to the motor rotating speed. The opening of a hydraulic pressure regulating valve is adjusted by energization control to regulate the hydraulic pressure of the wheel cylinder. A control means obtains control characteristics representing a relationship among the motor rotating speed, the energizing current value to the hydraulic pressure regulating valve, and the hydraulic pressure of the wheel cylinder based on the hydraulic pressure of the wheel cylinder when the energizing current value to the hydraulic pressure regulating valve is changed while maintaining a constant motor rotating speed.
