Disclosed is a check valve of a hydraulic brake system. The check valve includes a valve housing which includes an inner-diameter portion configured to support a ball, an expanded cylindrical body portion and an outer-diameter portion circumferentially extending from the body portion, and a valve seat which includes a first body portion extending in a bent shape from an oil hole and configured to support the spring therein, a second body portion having a greater diameter than the first body portion and press-fitted to the body portion of the valve housing, a third body portion circumferentially extending from the second body portion to come into surface contact with the outer-diameter portion and be press-fitted into an inner stepped portion of a perforated block. The check valve having a simplified configuration achieves size and weight reduction and is manufactured at low cost and high processing efficiency using pressing.
