PROBLEM TO BE SOLVED: To provide a solenoid valve capable of increasing a fuel flow rate and improving the valve closing responsiveness and a fuel supply device using it. SOLUTION: If a notch section 70a, which is a part of the ring provided on the side of the outer periphery of a stopper plate 70 for restricting the moving distance of a valve element 40 in the direction to open a valve resisting the energizing force of an energizing spring 60 is arranged to the plate 70 in a ring like state, the fuel sucked from a fuel inlet port 52 in sucking the fuel can be increased and discharged downstream. Since the face SS where the plate 70 and a large diameter section 43 abut on each other is formed into a circle, and a radial direction slit 70s which discontinues the face SS is provided, changes in outer fuel supply force can be immediately propagated to the inner fuel of the face SS, as a result, since fuel supply force is made to work on the lower bottom face of the large diameter section 43 together with the suction force of an electromagnetic drive section IS, valve closing responsiveness can be improved. |
