To reduce the number of switching elements for driving a solenoid valve.

In a solenoid valve driving device 1 for overexcitation driving first and second solenoid valves 2, 3 at a time lag and then holding and driving them, first and second control circuits 6, 7 are provided with a high side switching element for outputting a first control signal C1 to overexcitation drive the solenoid valves and a second control signal C2 to hold and drive them and for carrying a holding current from a DC power supply 4, so that high voltage HV can be supplied to respective DC power supply sides of the high side switching element via a common switching element 9 to be open in response to either of the first control signal C1.
