Abstract:
An electrolytic capacitor includes an anode body, a dielectric layer formed on the anode body, and a conductive polymer layer covering at least a part of the dielectric layer. The conductive polymer layer includes a conductive polymer and a polymer dopant. The polymer dopant includes a first copolymer including: (A) a first unit derived from a first monomer having a sulfonate group; (B) a second unit derived from a second monomer having a carboxy group; and (C) a third unit derived from a third monomer having a hydroxy group.
