ABSTRACT:
The present invention provides a paste for forming an internal electrode in a ceramic element. The paste causes no sudden heat generation from an organic vehicle contained therein during a degreasing step and allows Pd or Ag/Pd serving as an internal electrode to expand freely as a result of oxidation during a firing step, to thereby prevent structural defects of the ceramics such as delamination, when used for the formation of internal electrodes in a ceramic element such as a laminated ceramic capacitor. The paste contains a metal powder of Pd or Ag/Pd, Pd resinate, Cr resinate and an organic vehicle. Preferably, the Pd resinate contains sulfur in the molecule. Also preferably, the paste contains the Pd resinate in an amount of about 2.0-3.0 parts by weight as Pd, based on 100 parts by weight of Pd in the metal powder, and the Cr resinate in an amount of about 0.03-0.12 parts by weight as Cr.sub.2 O.sub.3, based on 100 parts by weight of the metal powder.
