PROBLEM TO BE SOLVED: To provide a solenoid valve control device for preventing a member as part of a valve part from being in a constantly one-direction magnetized condition. SOLUTION: The solenoid valve control device comprises an electromagnet for attracting a piston (a valve element) to one side independently of the energizing direction of a coil 8. Herein, control means (a H-bridge circuit consisting of power MOSFETs 21-24 and a control circuit 25 for controlling it to change the energizing direction of the coil 8 at starting system, e.g.) is provided for alternately switching the energizing direction of the coil 8.
