PROBLEM TO BE SOLVED: To reduce a size and a weight of a solenoid valve as a whole, by reducing a size of a valve element.SOLUTION: A solenoid valve 1 includes: a valve body 40 made of resin, and having a valve chest 45 communicated with an inlet port 41a and a first outlet port 42a; a valve element 64 disposed in the valve chest; a valve holder 60 made of a magnetic material and holding the valve element; a coil spring 66 for biasing the valve holder to the direction of the first outlet port; a pipe member 10 made of resin, having a second outlet port 10a communicated with the valve chest, and extending above from the valve chest; an attractor 50 surrounding the pipe member; a coil bobbin 20 made of resin, for winding an electromagnetic coil 21 surrounding the attractor; and a mold cover 30 made of resin, surrounding the entire coil bobbin, integrated with the valve body, and defining the valve chest by the valve body, the pipe member and the coil bobbin. The valve holder has a cylindrical body 61 opposed to the attractor, and a small cylindrical portion 62 having a diameter smaller than that of the cylindrical body, having a fluid insertion hole at its intermediate portion, and having a holding portion for holding the valve element at the inside of its tip. |
