A

PROBLEM TO BE SOLVED: To provide a solenoid valve capable of being assembled with a smaller number of components and man-hours without degrading blocking performance.SOLUTION: A solenoid valve 1 includes an electromagnetically-driven valve shaft portion 11, a valve body 15 disposed on a tip of the valve shaft portion 11, a coil spring 18 for biasing the valve body 15 from a valve seat 14 side, and a regulating member 22 having a regulating plane 22b covering a face on a side opposite to a valve seat 14, of the valve body 15. The valve shaft portion 11 includes an annular projecting portion 11b for regulating movement of the regulating member 22 to a rear end direction, a radial supporting portion 11c for radially supporting the regulating member 22, and an annular recessed portion 11d for holding the valve body 15 through a mounting hole 15a. The valve body 15 includes a small-diameter thick portion 15b, an annular groove portion 15e, an annular inclined portion 15d, and a large-diameter thick portion 15c from a radial inner side toward an outer side.
