Abstract: It is a solenoid valve used in hydraulic control. Inside a body 4, a clip plate 11 is provided at the side of an inlet 5. The clip plate 11 is formed integral by a circular support portion 12 and three retaining pawls 13 extending toward its center. On the other hand, a filter 21 of synthetic resin is formed integral by an outer frame portion 22 encircling the inlet 5, an inner frame portion 23 bisecting it and filter portions stretched therebetween. Further, a retaining convex portion 25 projecting toward the inlet 5 is provided at an intermediate portion of the inner frame portion 23. The inner frame portion 23 is elastically deformed to move the retaining convex portion 25 toward the side of the inlet 5 so that it is retained by the three retaining pawls 13 of the clip plate 11. The shape can be achieved wherein the filter 21 does not project so much from the body so that the overall size of the solenoid valve can be reduced.
