Module

A module for supplying a direct-current voltage adjusted by a voltage regulator including a semiconductor active element to a load, the module comprising:

• a capacitor layer that includes at least one capacitor portion that forms a capacitor that includes an anode plate comprising a metal;
• a through-hole conductor that penetrates the capacitor portion in a thickness direction of the capacitor layer;
• and
• a connection terminal disposed on a surface of the through-hole conductor and that is configured to provide an electrical connection for at least one of the voltage regulator and the load,
• wherein the through-hole conductor electrically connects the capacitor to at least one of the load and the voltage regulator,
• wherein the through-hole conductor is interposed between the load and the voltage regulator,
• wherein the through-hole conductor includes a first through-hole conductor disposed in at least an inner wall surface of a first through-hole penetrating the capacitor portion in the thickness direction,
• wherein the first through-hole conductor is electrically connected to an end surface of the anode plate,
• wherein the anode plate includes a core portion and a porous portion disposed on at least one main surface of the core portion,
• wherein the core portion and the porous portion are exposed on the end surface of the anode plate connected to the first through-hole conductor, and
• wherein an outer peripheral length of the first through-hole conductor located at the porous portion is longer than an outer peripheral length of the first through-hole conductor located at the core portion.
