摘要： Provided is an electrolytic capacitor having a cathode that exhibits a high capacity. The electrolytic capacitor includes: a cathode having a conductive substrate and a conductive polymer layer placed on a surface of the conductive substrate; an anode having a substrate composed of a valve metal and a dielectric layer composed of an oxide of the valve metal that is placed on the surface of the substrate and is so placed that the dielectric layer and the conductive polymer layer of the cathode face each other through a space; and an ion-conductive electrolyte filled in the space, in which the conductive polymer layer of the cathode that is in contact with the ion-conductive electrolyte expresses a redox capacity by applying a voltage between the anode and the cathode.

摘要： Provided is a polymerization liquid for electropolymerization, which uses a solvent that is mainly composed of water, which is greatly increased in the amount of a monomer contained therein, and which is capable of quickly forming a conductive polymer layer having high conductivity and heat resistance, A polymerization liquid for electropolymerization of the present invention contains: a solvent that is composed of 100-80% by mass of water and 0-20% by mass of an organic solvent; at least one monomer having a pi-conjugated double bond; at least one supporting electrolyte; and at least two nonionic surfactants. The at least two nonionic surfactants are composed of at least one acetylenol surfactant and at least one water-soluble nonionic surfactant other than the acetylenol surfactant. Due to the combination of the two nonionic surfactants, the amount of the monomer emulsified with the solvent can be greatly increased.
