An integrated electro-hydraulic brake system includes a power source unit storing a pressure, discharging oil from a reservoir to an accumulator, and a motor driving the pump; and an integrated hydraulic control device including a master cylinder and generating a hydraulic pressure, a reservoir connected above the master cylinder and storing oil, an in-valve and an out-valve controlling pressure delivered from the accumulator to a wheel cylinder. The power source unit is provided as a separate unit to isolate operating noises, and the integrated hydraulic control device and the power source unit are connected by an external pipe, and the out-valve is provided as a normally open type-solenoid valve that is used at low current ranges, normally maintains an open state in order to reduce heat generation, but is closed when a close signal is received, compared to a normally close type-solenoid valve that normally maintains a close state.
