Abstract: An electrolytic capacitor including a capacitor element that includes an anode body being porous, a dielectric layer formed on the surface of the anode body, and a solid electrolyte layer covering at least part of the dielectric layer. The anode body has a plurality of principal surfaces and a corner portion. The corner portion includes a plurality of side portions connecting between the principal surfaces, and one or more vertex portions connecting between the principal surfaces. A surface layer X of at least part of the corner portion is more compact in texture than a surface layer Y of the principal surface adjacent to the surface layer X.

Abstract: An electrolytic capacitor includes a capacitor element including a porous anode body, an anode wire partially embedded in the anode body, a dielectric layer formed on a surface of the anode body, and a solid electrolyte layer covering at least a portion of the dielectric layer, wherein the anode body is formed of a first metal, the anode wire is formed of a second metal having a different composition from the first metal, and the second metal has a conductivity S2 that is larger than a conductivity S1 of the first metal. This allows for providing an electrolytic capacitor which suppresses an increase in production costs and has a low ESR.

Abstract: An electrolytic capacitor includes an anode body having a porous structure, an anode lead partially embedded in the anode body, a dielectric layer formed on a surface of the anode body, and a cathode part that covers at least part of the dielectric layer. The anode body has a first region in which first particles sintered together and a second region in which second particles sintered together. The average particle diameter D1 of the first particles is smaller than the average particle diameter D2 of the second particles. The volume-based pore diameter distribution of the anode body with the dielectric layer has a first peak in a range of less than or equal to 0.5 μm in pore diameter, and a second peak in a range of more than 0.5 μm in pore diameter.
