The present invention discloses a hydraulic unit of an anti-lock brake system for vehicles having a housing (20) that is easily manufactured, whereby production efficiency is improved, and thus the manufacturing costs of the housing are reduced. The present invention also discloses a method of manufacturing the same. The hydraulic unit comprises a housing (20) having components that control braking oil pressure supplied to wheels of a vehicle, such as a plurality of valves (12,13), accumulators (14,17), and hydraulic pumps (15), mounted thereto, flow channels (29) formed in the housing (20), the flow channels being connected between the components, and a plurality of pipes connected to each other in the housing. The housing (20) is made of an injected resin material having a plurality of reinforcing members (30) that reinforce the strength of the parts of the housing where the components are mounted to the housing (20) and the pipes are connected to the housing inserted therein. Alternatively, the housing is made of an injected resin material having tube-shaped flow channel members (50) inserted therein, such that the flow channels are formed. <IMAGE>
