Abstract
A solid electrolytic capacitor includes: a porous sintered body made of a valve metal; an anode wire that has a portion extending inside the porous sintered body, and that protrudes from the porous sintered body; a dielectric layer formed on the porous sintered body; a solid electrolyte layer formed on the dielectric layer; a cathode layer formed on the solid electrolyte layer; and a protective film having at least a portion formed on the cathode layer. The protective film has a glass transition point of 180° C. or lower.
