Abstract
An electrolytic capacitor includes; an anode body including a porous body, a dielectric layer; and a solid electrolyte layer that fills in pores of the porous body. A filling rate R of the solid electrolyte layer in the porous body decreases from an outer surface toward the center. A shortest distance D from an outer surface to the center, and a distance Xfrom the outer surface of the porous body when the filling rate R is 50% satisfy a specific relationship. When CV value of the porous body is less than 100,000 μF·V/g, 0.1 D≤X<0.7 D is satisfied. When CV value of the porous body is 100,000 μF·V/g or more and less than 150,000 μF·V/g, 0.05 D≤X<0.3 D is satisfied. When CV value of the porous body is 150,000 μF·V/g or more, 0.03 D≤X<0.2 D is satisfied.
