摘要:
An electrolytic capacitor includes an anode body, a dielectric layer that covers the anode body, a first solid electrolyte layer that covers the dielectric layer, and a second solid electrolyte layer that covers the first solid electrolyte layer. The first solid electrolyte layer contains a first conductive polymer that includes polypyrrole as a basic skeleton. The second solid electrolyte layer contains a second conductive polymer that includes polythiophene as a basic skeleton. The second solid electrolyte layer has a thickness of 1 μm or more.
