ABSTRACT:
A ceramic capacitor having an improved electrode soldering performance, little or no diffusion of solder even in the case of being used under a high temperature environment and a reduced characteristic deterioration is provided. The dry plating electrodes have a three-layer structure. First layers of the electrodes are respectively provided on both surfaces of a ceramic element assembly and made of any one or more of Cu, Ni--Cu alloy and Zn. Second layers of the electrodes are respectively provided on the surfaces of the first layers and made of a material different from the material of the first layers and any one or more of Cr, Ni--Cr alloy, Fe--Cr alloy, Co--Cr alloy, Ti, Zn, Al, W, V and Mo. Third layers of the electrodes are respectively provided on the surfaces of the second layers and made of any one or more of Cu, Ni--Cu alloy, Ag and Au.
