To prevent a rubber seal member from being adhered to a valve seat section and prevent the occurrence of wear and crack in the rubber seal member.

A solenoid valve 11 has a casing 13a, valve seat sections 16, 17, a rubber seal member 15, and a plunger 6. The valve seat sections 16, 17 are formed on an inner wall face of the casing 13a. The rubber seal member 15 comes into contact with and is separated from the valve seat sections 16, 17 due to the drive of the plunger 6. On the inner wall face of the casing 13a, a compound plated layer 18 in which fluororesin particles are dispersed in metal matrix containing Ni is formed.
