Abstract:
The present invention comprises: a base material that contains a valve action metal; and a differing metal composite layer that covers the surface of the base material. The differing metal composite layer includes a mixed region in which a first metal and a second metal differing from the first metal exist. The mixed region constitutes at least 50% of the differing metal composite layer in the thickness direction. A high-performance and highly reliable electrolytic capacitor is provided by using an electrode foil for electrolytic capacitors wherein, in the mixed region, the content ratio M1 of the first metal to all metals and the content ratio M2 of the second metal to all metals are each not less than 1 at.%.
