A solenoid valve for a brake system capable of being easily manufactured with reduced manufacturing costs is disclosed. A valve seat member has an inner passage formed through the valve seat member in a longitudinal direction thereof, an outer passage formed on an outer surface of the valve seat member in the longitudinal direction, and a seat portion formed with a first orifice above the inner passage. The seat portion is formed unitarily with the valve seat member. A sleeve is coupled on the outer surface of the valve seat member. The sleeve has a flange portion to be fixed to a modulator block. A valve core is coupled to a portion of the sleeve, opposite to the flange portion. An armature is slidably mounted in the sleeve. The armature has an opening/closing portion to open or close the first orifice. A restoring spring presses the armature toward the first orifice.
