PURPOSE: A solenoid valve is provided to minimize contaminants, contained in fluid from a valve part, flowing into a solenoid part by forming a ring-shaped filter between the valve part and the solenoid part. CONSTITUTION: A solenoid valve comprises a solenoid part(200), a valve part(100), a ring-shaped filter(160). The valve part is operated by the operation of the solenoid part. The ring-shaped filter is arranged between the solenoid part and the valve part. The valve part has a hollow holder(110) and a spool(120). One or more chambers and ports are formed in the holder. The spool is vertically reciprocated inside the holder.
