PURPOSE: To provide a laminated porcelain capacitor having an improved withstand voltage property and the suppressed generation of delamination as the one useable for a circuit element for a micro, thin, and light electronic device.
CONSTITUTION: An electrode layer 12 is arranged on the surface of a support 11. On this surface, a green sheet is produced by the two dielectric thin layers 13a and 13b which are formed by use of dielectric powders having different average granular diameters. Then, the dielectric layer 13 constituting the green sheet and the electrode layer 12 are heat transferred by a hot press for lamination to a laminated porcelain capacitor. In this case, since the powder having the larger granular diameter is used for the dielectric thin layer 13b, the amount of an organic coupling agent required for the heat transfer can be small. Accordingly, the removal of the organic coupling agent is easy, thus enabling the generation of delamination to be suppressed. On the other hand, the dielectric thin layer 13a formed by the powder of a smaller granular diameter is excellent in sinterability, and is finely sintered to provide an excellent withstand voltage property.
