Capacitor element

A capacitor element, comprising:

• a capacitor portion including:
• an anode plate including a core portion and a porous portion at at least one main surface of the core portion,
• a dielectric layer at a surface of the porous portion, and
• a cathode layer at a surface of the dielectric layer;
• a seal layer covering the capacitor portion;
• a first through-hole conductor extending through the capacitor portion and the seal layer in a thickness direction and electrically directly connected to the anode plate, and having two end portions drawn out to a surface of the seal layer;
• a second through-hole conductor extending through the capacitor portion and the seal layer in the thickness direction and electrically directly connected to the cathode layer, and having two end portions drawn out to the surface of the seal layer;
• a first outer electrode layer at the surface of the seal layer and electrically connected to the first through-hole conductor, wherein at least a part of the first outer electrode layer overlaps the cathode layer in the thickness direction;
• and
• a second outer electrode layer at a surface of the seal layer and electrically connected to the second through-hole conductor.
