Title:
LAMINATED CERAMIC CAPACITOR AND ITS MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2005235976
Kind Code:
A
Abstract:

To provide a laminated ceramic capacitor in which, even at the side face of a laminated ceramic capacitor element, a generation start voltage of creeping discharge is raised sufficiently and a withstand voltage is high.

A discharge suppressing electrode 12 which mitigates an electrolytic concentration on the surface of a dielectric ceramic 8 is provided in a plane state in the lamination direction of a capacity forming electrodes 9a to 9i and in the longitudinal direction of a laminated ceramic capacitor element 10. By this structure, the discharge suppressing electrode 12 can take a sufficient area without being alternately laminated with the dielectric ceramic 8. As a result, the electrolytic concentration on the surface of the ceramic is mitigated, and in particular, it is possible to provide a laminated ceramic capacitor 7 which sufficiently suppresses the creeping discharge at the side face of the ceramic capacitor element 10 at a high withstand voltage.
