Title: CAPACITOR AND METHOD FOR MANUFACTURING CAPACITOR
Abstract:
This capacitor is provided with: a positive electrode; an oxide layer; a dielectric layer; and a negative electrode. The oxide layer is positioned between the positive electrode and the dielectric layer. The positive electrode comprises a Zr alloy (ZrM, where M is a metallic element that can form an oxide film in an electrolytic solution). The oxide layer includes a ZrM composite oxide ((ZrM)OY, where Y<2) that has a hexagonal closest packing structure. The dielectric layer includes a ZrM composite oxide ((ZrM)O2).
