1. A ceramic capacitor comprising:
an internal electrode formed of a conductive paste on a dielectric, the conductive paste comprising:
metal particles; and
a metal oxide additive;
wherein the metal oxide additive includes a metal oxide having, in an Ellingham diagram, a higher level of standard Gibbs energy of formation than carbon dioxide or carbon monoxide at a temperature of 500 to 1000° C., and
the metal oxide additive includes two or more metal oxides.
