PURPOSE: To provide a method for manufacturing a ceramic capacitor, in which its shape can be simply applied.
CONSTITUTION: A ribbon of an alloy of Cu and Al is manufactured. When the ribbon of the Cu-Al alloy is oxidized, Cu-Al-O composite oxide layers are formed on both side surfaces of the alloy, and a CuO layer is formed at the outside of the oxide layer. The oxide layer and the CuO layer are reduced to obtain a laminate having a Cu-Al2O3-(Cu-Al alloy)-Al2O3-Cu laminar structure. The laminate has a porcelain dielectric of an Al2O3 layer on the surface of the Cu-Al alloy, and the outside of the Al2O3 layer is a conductor of a Cu layer. When the Cu-Al alloy and the Cu layer are used as electrodes of a capacitor, the CO-Al2O3-(CO-Al-alloy)-Al2O3-Cu becomes a laminated ceramic capacitor. Further, a shape is applied to a winding structure before or after oxidizing and reducing processes.
