CAPACITOR

摘要

The present invention provides a highly reliable capacitor which is unlikely to be affected by impurities on the surface of a porous metal base material, and small in leakage current. The capacitor according to the present invention includes a porous metal base material, a first buffer layer formed by an atomic layer deposition method on the porous metal base material, a dielectric layer formed by an atomic layer deposition method on the first buffer layer, and an upper electrode formed on the dielectric layer.
