Capacitor

A capacitor comprising:

• a capacitor layer including a capacitor part, the capacitor part having a first through-hole extending through the capacitor part in the thickness direction and defining an inner wall surface, wherein the capacitor part includes:
• an anode plate including a core part and a porous layer on at least one major face of the core part, the porous layer including a first void,
• a dielectric layer on a surface of the porous layer, and
• a cathode layer on a surface of the dielectric layer;
• and
• a first through-hole conductor disposed at least on the inner wall surface of the first through-hole, wherein the first through-hole conductor is electrically connected to an end face of the anode plate that faces the inner wall surface of the first through-hole in a plane direction, the plane direction being a direction of a plane perpendicular to the thickness direction, and the first void contains at least part of the first through-hole conductor.
