Beschreibung
Zusammenfassung:An electrolytic capacitor includes an anode body formed with a dielectric layer on a surface thereof, a cathode body formed with a nickel layer on a surface thereof, and a solid electrolyte formed between the anode body and the cathode body. The solid electrolyte contains a conductive polymer. The nickel layer contains a nickel crystal grain whose length in a direction perpendicular to a thickness direction of the nickel layer in a cross section taken in the thickness direction is 50 nm or more.
