PURPOSE:To reduce the change rate of an electrostatic capacity and to improve reliability by applying a polarizable electrode and a collecting electrode with a silicate compound conductive inorganic bond layer containing conductive substance such as silicate alkali, graphite, carbon black, etc. CONSTITUTION:Silicate compound conductive inorganic bond layers 12, 12' for applying both polarizable electrodes 11, 11' and conductive collecting electrodes 13, 13' are provided therebetween. The layers 12, 12' contain silicate compound substance and conductive substance. The silicate compound includes as main ingredient silicate alkali represented by a formula X2.SiO2 (where X is alkali metal, n is 0.5-8). The conductive substance used includes graphite, furnace black, etc., by a furnace type incomplete combustion method. The conductive inorganic bond is applied to one or both of the polarizable electrode or electrode material before impregnating with electrolyte, the collecting electrodes, both are superposed as they are or under pressure in an undried state, then dried, and solidified to form the layers 12, 12'. |
