PROBLEM TO BE SOLVED: To prevent an interface of an electrode and a dielectric from being made thermally unstable owing to the diffusion of Bi in Bi-based dielectric material into the electrode under a high-temperature condition in a manufacturing process or use.SOLUTION: The above problem can be solved by an electrode in contact with a Bi-based dielectric material, which is arranged so as to include an element hard to diffuse. Specifically, the following can be used as such element: beryllium, magnesium, calcium, strontium, barium, scandium, yttrium, lanthanum, titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, zinc, aluminum, gallium, indium, thallium, sulfur, germanium, tin, arsenic and antimony. A capacitor according to the arrangement like this can be preferably used for e.g. a motor vehicle.SELECTED DRAWING: None |
