JPS6454720A - Manufacture of laminated type ceramic chip capacitor - Google Patents

Abstract

PURPOSE:To improve the stability of the connection of an internal electrode layer and an external electrode layer by interposing and connecting a metal of a different kind between the internal electrode layer and the external electrode layer exposed to the sidewall surface of both ends of an element. CONSTITUTION:Conductive paste mainly comprising a metal Pd is applied onto the surface of a ceramic dielectric 4 processed to a sheet shape to a desired figure shape, and a required number of the sheets are laminated and monolithic- molded, cut and worked, and baked, thus manufacturing a piece-shaped capacitor element. Electroless plating metallic layers 6 are attached to the broken-out section and peripheral section of an exposed stratiform internal electrode layer 5 in the capacitor element. The layer 6 used at that time is composed of a metal different from the layer 5. Conductive paste mainly comprising silver is applied selectively so as to coat the layers 6 at a pair of opposed both end sections of the capacitor element, and baked at a high temperature, thus forming external electrode layers 7. Accordingly, the stability of the connection of the layers 5 and the layers 7 is improved.
