In particular, from the viewpoint of moldability, the content of the latex is preferably in the range of 25 to 40% by weight. However, increasing the amount of latex does not significantly change the conductivity. This is due to the presence of latex particles between the carbon-based powders to an extent that does not inhibit contact between the carbon-based powders.

Since it is not covered with a material, the surface activity of the carbon-based powder is not impaired. Therefore, the decrease in the specific surface area of the carbon-based powder is extremely small, the electrical conductivity is good, and as a result, a large capacitance can be obtained in the presence of an electrolyte solution.
Furthermore, since this polarizable electrode is solid and can be handled as a solid object, it has the advantage that it can be easily accommodated in the holes of the insulating member. Furthermore, since a fixed volume of polarizable electrodes can be mass-produced, there is no variation in the amount of pasty polarizable electrodes when filling them, unlike in the past, and variations in characteristics between products can be suppressed. Furthermore, the equivalent series resistance (ES
R.) also has the effect of being small.
