See full text

A disclosed capacitor element includes: a first electrode; a dielectric layer covering at least a portion of the first electrode; and a second electrode covering at least a portion of the dielectric layer. The second electrode includes a solid electrolyte layer, a conductive carbon layer covering at least a portion of the solid electrolyte layer, and a metal paste layer covering at least a portion of the carbon layer. The carbon layer includes flake carbon particles and spherical carbon particles. A particle diameter of the spherical carbon particles is less than an average major diameter of the flake carbon particles, or greater than or equal to the average major diameter of the flake carbon particles.
