1. An electrolytic capacitor comprising a capacitor element and a liquid component,
the capacitor element including:
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, wherein;
the conductive polymer includes a first monomer unit corresponding to a 3,4-ethylenedioxythiophene compound and a second monomer unit corresponding to a 3,4-dialkoxythiophene compound, and
a ratio of the second monomer unit in the conductive polymer ranges from 1.0 parts by mass to 15 parts by mass, inclusive, with respect to 100 parts by mass of the first monomer unit.
