A valve block for an electronic brake system is disclosed. The valve block is configured to have two hydraulic circuits, a plurality of accommodating bores in which valves, pumps, low pressure accumulators, pressure sensors, and a motor are installed in order to control the braking hydraulic pressure supplied from a master cylinder to a wheel cylinder installed in each wheel, and a plurality of flow passages for connecting the plurality of accommodating bores, wherein on opposite side surfaces of the valve block, pump accommodating bores are formed symmetrically to each other to accommodate the pump, and first damping bores having an arrangement parallel to the pump accommodating bores are formed above the pump accommodating bores, wherein on an upper surface of the valve block, a pair of second damping bores is formed so as to be positioned above the first damping bores, and wherein first hydraulic lines are formed in a straight line from a bottom surface of the pair of second damping bores toward a bottom surface of the valve block, so that a discharge side of the pump accommodating bores and a suction side of the first damping bores, and a discharge side of the second damping bores and the bottom surface of the second damping bores are connected by the first hydraulic lines.
