Abstract:
Disclosed is an electrolytic capacitor including a capacitor element 10. The capacitor element 10 includes: a separator 23; a foil-like anode body 21 and a foil-like cathode body 22 that face one another so as to sandwich the separator 23; and an electrolyte layer that is in contact with the anode body 21, the cathode body 22, and the separator 23. The electrolyte layer contains: a first compound that is at least one compound chosen from the group consisting of sugars and polyvalent alcohols and that has a melting point of 50°C or above; and a first electrically conductive polymer. The electrolyte layer includes an unevenly distributed section in which the first compound is unevenly distributed.
