Abstract

PURPOSE:To improve a dryness resistant property of an electrolytic liquid by making the electrolytic liquid to contain polyhydric alcohol and/or its derivative. CONSTITUTION:An electrolytic liquid is made to contain polyhydric alcohol and/ or its delivative. Polyhydric alcohol and/or its delivative is dissolved in the electrolytic liquid of an aqueous solution system while having small vapor pressure. Accordingly, vapor pressure of the electrolytic liquid containing polyhydric alcohol and/or its delivative gets to be small. A dryness resistant property of the electrolytic liquid the more content gets higher while relatively reducing the amount of the electrolytic liquid so that an excessive content is not desirable. Commonly, a weight ratio of about 20-50% to the electrolytic liquid is sufficient on the whole.
