Electrolytic capacitor comprising an electrolytic solution containing a first base component, a first acid component, and a second acid component

An electrolytic capacitor comprising:

• an anode body having a dielectric layer disposed on a surface of the anode body;
• a solid electrolyte layer that is in contact with the dielectric layer, the solid electrolyte layer including a conductive polymer;
• and
• an electrolytic solution, wherein:
• the electrolytic solution contains a first base component, a first acid component, and a second acid component,
• the first base component includes an amidine compound,
• the first acid component includes a composite compound of an inorganic acid and an organic acid,
• the second acid component includes at least one selected from a group consisting of boric acid, phosphoric acid, phosphorous acid, hypophosphorous acid, and phosphonic acid, and
• a content proportion of the second acid component in the electrolytic solution ranges from 3 wt % to 15 wt %, inclusive.
