PROBLEM TO BE SOLVED: To suppress the damage of an O-ring mounted on the outer peripheral surface on the fuel inflow side of a magnetic cylinder element. SOLUTION: A large diameter flange part 21D having diameter larger than that of a flange part 3D of the magnetic cylinder element 3 is situated by using a resin material softer than the magnetic element 3. The large diameter flange part 21D having its outer peripheral edge protruded to the outer peripheral side from the outer peripheral edge of the flange part 3D of the magnetic cylinder element 3 throughout its whole periphery in a state to make contact with the flange part 3D of the magnetic cylinder element 3. This constitution brings an O-ring 18 into only contact with the outer peripheral edge part of the large diameter flange part 21D, when the O-ring 18 is mounted on the outer peripheral surface on the fuel inflow side of the magnetic cylinder element 3, prevented from the damage resulting from contact with the outer peripheral edge part of the large diameter flange part 21D, and smoothly mounted on the outer peripheral surface of the magnetic cylinder element 3.
