PROBLEM TO BE SOLVED: To reduce costs and suppress current loss by arranging an eliminating line which is common with a plurality of double coil magnetic valves for injecting fuel, and connecting the eliminating line to a cathode terminal connected to two diodes which are directly connected in the reverse direction at each magnetic valve. SOLUTION: A plurality of, for example, four double coil magnetic valves (DS-HDEV) 1 to 4 for injecting fuel in an internal combustion engine, one side end parts of first and second magnetic coils SPAUF, SPZU are mutually connected, and are connected to a common current supplying voltage Ubatt. The other end parts are individually connected to first and second low side switches S11 to S42, and each low side switch is controlled by a driver circuit TR. Eliminating motion of each valve 1 to 4 is carried out through a common eliminating line L1, and the line L1 is connected to a cathode terminal mutually connected to two diodes D11 to D42, and an anode terminal of the diode D is connected to the low side switch.
