In the operation of the invention described in claim 1, since the first and second members are connected by the conductive liquid such as water interposed therebetween, the two members are connected to each other. While there is a maximum voltage, almost no current flows between adjacent two members, and the amount of current is minimal.For example, the amount of current that flows in water is extremely small even if the hardness of water is high, and calcium, magnesium, silica in water, etc. It effectively prevents crystallization of the salt of and its precipitation.
