Abstract: There is disclosed a solenoid valve which is capable of effectively eliminating or inhibiting occurrence of an operational defect due to adhesion of a main valve body to a valve holder. A solenoid valve 40 includes a valve body 54 having a valve chamber 58, an inflow port 61, an outflow port 62, a valve seat 59 and a valve holder 72, a main valve body 67 movably disposed in the valve chamber, and a solenoid coil 51. Controlling of energization to the solenoid coil provides a state where the main valve body is in contact with the valve seat to cut off communication between the inflow port and the outflow port and a state where the main valve body is in contact with the valve holder to provide the communication between the inflow port and the outflow port. A removed portion is formed on an inner side of an end face of the main valve body 67 which is in contact with the valve holder 72, and a relation of Sd>SD×0.7 is satisfied.
