PROBLEM TO BE SOLVED: To provide a solenoid valve equipped with a valve which has excellent reliability and can be formed reasonably.SOLUTION: The solenoid valve includes: a solenoid part A for controlling a plunger 3 in reciprocating movements by applying electricity; a cylindrical sleeve 7 mounted in a state of being inserted to a target object 1 for mounting and having a plurality of fluid communication holes in a peripheral wall part; and a cylindrical resin made valve 6 capable of sliding freely along an inner peripheral face of the sleeve 7. The valve 6 is composed of a plurality of annularly shaped lands L formed to be protruded, including a small diameter land L2 which is placed at the outermost side in the direction of the axial direction of the valve and does not become slidingly contact with the inner peripheral face of the sleeve 7, and a large diameter land L1 which becomes slidingly contact with the inner peripheral face of the sleeve 7; wherein a first drain hole 61 is formed in a cylindrical wall part 62 disposed between the small diameter land L2 and the large diameter land L1 in order to communicate to the central space of the valve 6, and a second drain hole 73 is formed in a peripheral wall part 71 of the sleeve 7 facing the first drain hole 61 in order to communicate to the space at the side of the target object 1. |
