PURPOSE: A solenoid valve is provided to reduce sliding hysterias and fluid fixing of a sliding part in the case where a valve element is driven in valve control, and carry out a stable operation having high reliability by carrying out support with a sliding supporting part and a sliding supporting part with respect to a plunger. CONSTITUTION: A solenoid valve(1) is integratedly formed in such a constitution that a valve rod(5) is composed of a valve element(3b), and a solenoid side rod(5c) and a bellows side rod(5e) on both ends, and the solenoid side rod(5c) is connected to a plunger(2b). Accordingly, both end parts of the valve rod(5) are supported at two points of an inner circumferential surface of a sleeve(2d) and an inner cylindrical part(4a) of a valve body(4), and thereby, a sliding resistance is reduced, and furthermore, a stable operation is carried out. Furthermore, it is possible to reduce the number of parts, it is possible to improve assemblage, and it is also possible to reduce costs.
