The electromagnetic valve operates in a closed valve state in which the valve body is brought into contact with the valve seat by application of a spring force and an open valve state in which an electric current is passed through a coil (16) and the valve body is separated from the valve seat by a magnetic force. The fixed magnetic core (15) has a U-shape and magnetic attraction surfaces (26) are provided on both ends thereof. The resin case (17) into which the fixed magnetic core (15) and the coil (16) are incorporated is provided with a bottom surface (27) that exposes the magnetic attraction surfaces (26). A case contact surface (51) that protrudes past the magnetic attraction surfaces (26) toward the moving element is formed on the bottom surface (27) of the case (17). Resin films (52) are provided on the magnetic attraction surfaces (26). |
