The capacitor has a conductive layer, which is a dispersion of fine particles of graphite in a solidified polymer amounting to from 1 to 10% by weight of graphite, between and in intimate contact with a cathode and a solid electrolyte layer which is formed on an anodized valve metal and made of a semiconductive salt of 7,7,8,8-tetracyanoquinodimethane and a polymer. The conductive layer is formed by applying a suspension of graphite particles, the mean particle size of which preferably ranges from 1 to 7 mu m, in a solution of a polymer in a low viscosity and easily evaporable solvent, e.g. ethanol, onto the electrolyte layer followed by drying at or slightly above room temperature to evaporate the solvent and solidify polymer. |
