Electrolytic capacitor and method for manufacturing same

An electrolytic capacitor comprising:

• a capacitor element;
• and
• a liquid component, wherein:
• the capacitor element includes:
• an anode body including a dielectric layer on a surface of the anode body, and
• a conductive polymer covering a part of the dielectric layer,
• the liquid component contains a solvent, an inorganic acid, and an organic oxy compound,
• an amount of the organic oxy compound per mol of the inorganic acid is more than 0.5 mol,
• the organic oxy compound includes at least one molecular structure selected from the group consisting of:
• (A) two first carbon atoms adjacent to each other, each of the two first carbon atoms being a first carbon atom,
• (B) two second carbon atoms adjacent to each other, each of the two second carbon atoms being a second carbon atom,
• (C) a first carbon atom and a second carbon atom adjacent to each other, and
• (D) one or more second carbon atoms, each of the one or more second carbon atoms being a second carbon atom,
• where the first carbon atom is a carbon atom to which only one group selected from OH group or COOH group is bonded, and the second carbon atom is a carbon atom to which two or more groups selected from OH group or COOH group are bonded.
