PROBLEM TO BE SOLVED: To provide a brake fluid pressure control device capable of increasing the speed of a response of a solenoid valve irrespective of a drive mode of a pump, and favorably adjusting brake fluid pressure in a wheel cylinder. SOLUTION: An ECU 19 includes a main control unit 41 for detecting a pump discharge rate from a pump, a differential pressure command signal generation unit 50 for generating a differential pressure command signal IPsub for controlling linear solenoid valves 23a, 23b, a noise generation unit 51 for generating active noise RNa according to the pump discharge rate and an amplitude adjustment unit 52, a superposition determination unit 53 for generating a superposed command signal IPpluse by superposing the active noise RNa on the differential pressure command signal IPsub, and a DUTY ratio setting unit 54 for controlling the linear solenoid valves 23a, 23b according to the superposed command signal IPpluse.
