PROBLEM TO BE SOLVED: To provide a brake hydraulic pressure control device for a vehicle capable of restraining pulsation of hydraulic pressure and noise caused and generated by hunting of a constantly opened type proportional solenoid valve. SOLUTION: A control part 20 is furnished with an initial electric current value computing means 22 to compute an initial electric current value at which an inlet valve 1 starts opening in accordance with a pressure difference of upper and lower streams of the inlet valve 1 which is the constantly opened type proportional solenoid valve in transferring from a decompressed state or a held state to a pressure intensified state; a valve opening quantity increasing means 23 to increase valve opening quantity of the inlet valve 1 by lowering electrifying quantity from the initial electric current value; an offset required or not-required determining means 24 to determine whether it is required to offset the electrifying quantity to the increasing side for a prescribed period of time in accordance with a prescribed condition when the valve opening quantity increasing means 23 lowers the electrifying quantity; and an electrifying quantity offsetting means 25 to offset the electrifying quantity to the increasing side for a prescribed period of time at least once.
