To surely prevent infiltration of rainwater or the like into a solenoid from a cut line of a coating layer in one end side of a bobbin, in a solenoid valve.

A receiving part of a main unit receiving a solenoid assembly unit 14 is closed by a flange part 21b of a closing core 21. In the flange part 21b, the solenoid assembly unit 14 is supported through a rubber plate 22 annularly formed along a winding direction of a solenoid 16. By the rubber plate 22, rainwater or the like infiltrated in one end side of the solenoid assembly unit 14 is prevented from reaching to a cut line E of a coating layer 20 provided in the central side. Further, annular protrusive streak parts 20a, 20b protruded toward the rubber plate 22 continued in the winding direction of the solenoid 16 are formed in the coating layer 20, and a water-stopping property is made sure.
