ABSTRACT:
A metal capacitor with improved electric conductivity includes a metal member having a through-hole forming portion where a plurality of through-holes are formed, an electrode withdrawing portion formed on the through-hole forming portion, and a sealing portion. The metal capacitor includes a metal oxide layer being formed on the metal member and a main electrode layer formed on the metal oxide layer that is formed on the through-hole forming portion of the metal member, to fill the plurality of through-holes. The metal capacitor further includes an insulating layer formed on the main electrode layer and the metal member to externally expose the electrode withdrawing portion of the metal member.
