PROBLEM TO BE SOLVED: To provide a plunger type solenoid valve having reduced cost and size by using a plunger for sliding along a shaft to move a spool in the axial direction so that a valve port is controlled to be opened/closed with the movement of the spool. SOLUTION: The solenoid valve comprises the spool slidably inserted into a housing having a plurality of ports for opening/closing the ports, an energizing member for energizing the spool in one direction, and a boss fixed into a case forming a magnetic circuit arranged on one axial end side of the spool for supporting the spool passing therethrough. The plunger is supported on the shaft fixed into the case on the same axial line as that of the spool movably in the axial direction, and the end face of the spool is thrust against the front end face on one end side thereof.
