Solid electrolytic capacitor

A solid electrolytic capacitor comprising:

• a plurality of capacitor elements each including an anode portion composed of a metal layer extending in a first direction and having an external surface with a plurality of recesses, a dielectric layer on the external surface of the metal layer, and a cathode portion having a solid electrolyte layer on the dielectric layer and a current collector layer on the solid electrolyte layer, the plurality of capacitor elements being stacked in a second direction orthogonal to the first direction such that mutually adjacent capacitor elements have their respective current collector layers electrically connected to each other;
• a leading conductor layer connected to the current collector layer of only one capacitor element of the plurality of capacitor elements that is adjacent to the leading conductor layer;
• an insulating resin body covering the plurality of capacitor elements and the leading conductor layer, the insulating resin body having a first end surface and a second end surface opposite to each other;
• a first external electrode on the first end surface and electrically connected to the leading conductor layer;
• and
• a second external electrode on the second end surface and electrically connected to the metal layer of each of the plurality of capacitor elements.
