Disclosed is an electronic brake system. An electronic brake system according to an embodiment of the present invention comprises a liquid pressure supply device having a first pressure chamber and a second pressure chamber which are partitioned by a hydraulic piston. A hydraulic control unit, which controls the flow of liquid pressure supplied to first and second hydraulic circuits for controlling liquid pressure in a wheel cylinder, includes: a first hydraulic path for connecting the first pressure chamber and one of the first and second hydraulic circuits; a second hydraulic path branched from the first hydraulic path and connected to the other of the first and second hydraulic circuits; a third hydraulic path which is branched from the first hydraulic path on an upstream side of the branch point of the second hydraulic path, and connects the second pressure chamber; a fourth hydraulic path which is branched from the first hydraulic path on an upstream side of the branch point of the third hydraulic path, and connects the third hydraulic path; and a fifth hydraulic path connecting the third hydraulic path and the second hydraulic path.
