PROBLEM TO BE SOLVED: To provide a vehicular brake device capable of increasing the amount of energy recovered during regenerative braking while attaining the miniaturization, simplification and low cost of the whole device. SOLUTION: The vehicular brake device is provided with a motor M for driving drive wheels RL, RR of the vehicle, and performs regenerative braking making the motor M as a generator at regenerative braking. The vehicular brake device is provided with a master cylinder MC; a brake pedal BP interlocked with the master cylinder MC and operated by a stepping force of a driver; a booster BS for operating the master cylinder MC; wheel cylinders 5a-5d provided on respective wheels of the vehicle; and a first brake circuit 1 for feeding brake liquids which is pressure-raised by the booster BS to at least wheel cylinders 5a, 5b of driven wheels FL, FR. The liquid pressure of the brake liquid (fed to the driven wheels FL, FR) is reduced when performing regenerative braking, and regenerative brake forces of the drive wheels RL, RR are increased.
