There is provided a solenoid valve that realizes space-saving by reducing the size of a dedicated driving power source. There is provided a solenoid valve capable of instantaneously opening and closing that includes an electric double layer capacitor having a low direct current internal resistance and a low equivalent series resistance as a motive power supply. The electric double layer capacitor has single-cell electrical properties including a capacitance of 1 to 5 F, a rated voltage of 21 to 2.7 V, a direct current internal resistance of 0.01 to 0.1Omega, and an equivalent series resistance at 1 KHz of 0.03 to 0.09Omega, and includes a polarizable electrode made of glassy carbon having a specific surface area of 1 to 500 m2/g. |
