A magnetic core and a valve seat member having a valve opening for opening and closing a fluid flow path are disposed at two positions facing each other in the axial direction of the housing, and an excitation coil is arranged around the magnetic core. A plunger is arranged between the magnetic core and the valve seat member to close the valve port of the valve seat member with a spring biasing force, and to open the valve port in response to excitation of the excitation coil. 1. A solenoid valve, characterized in that a non-magnetic layer is interposed between contact surfaces of the plunger and the valve member. 2. The non-magnetic layer is comprised of a non-magnetic plate interposed between the contact surfaces of the plunger and the valve member, and the non-magnetic plate is fixed to at least one of the contact surfaces. A solenoid valve according to claim 1 of the utility model registration claim. 3. The utility model registered in claim 1, wherein the non-magnetic layer is made of a non-magnetic film coated on at least one of the contact surfaces of the plunger and the valve member. Solenoid valve.
