PROBLEM TO BE SOLVED: To provide a highly practical solenoid valve device.SOLUTION: A solenoid valve device includes a power supply 176; and a first connection path 200 and a second connection path 202 connecting two coils 130 and 132 of a solenoid valve 80, respectively. The solenoid valve device is configured to, if a current reduction is detected on one of the first connection path 200 and the second connection path 202, realize a current-carrying mode of using the other of the first connection path 200 and the second connection path 202 at a time of carrying a current to the solenoid valve 80 (a current-carrying-mode switching unit 250); to continuously carry a current high enough not to move a plunger to one of the first connection path 200 and the second connection path 202 while the current-carrying mode is realized (a current-reduced-connection-path current-carrying unit 254); and to discriminate whether the current reduction occurs instantly or continuously on the basis of a determination result as to whether the current reduction occurs during current carrying time (a current-reduced-state discrimination unit 256). |
