Electrolytic capacitor comprising an anode body including a porous body with a solid electrolyte layer provided therein

An electrolytic capacitor comprising:

• an anode body that includes a porous body and a dielectric layer covering the porous body, the porous body including a valve metal;
• and
• a solid electrolyte layer that covers the dielectric layer, the solid electrolyte layer being filled in a pore of the porous body, wherein:
• the porous body includes a first region and a second region other than the first region, the first region being located near an outer surface of the porous body,
• the first region is a region in which a distance from the outer surface of the porous body is shorter than 0.5D, where D is a shortest distance between the outer surface of the porous body and a center of the porous body,
• a filling proportion R2 of the solid electrolyte layer in the second region is less than a filling proportion R1 of the solid electrolyte later in the first region, and
• a ratio R2/R1 of the filling proportion R2 to the filling proportion R1 is less than or equal to 1/10.
