Abstract
A method of manufacturing a metal paste for an internal electrode according to the present invention includes preparing each of a metal powder and an organic vehicle; preparing a ceramic inhibitor powder in which a nano glass added with a rare-earth element is mixed; manufacturing a primary mixture by mixing the metal powder of 70 to 95 wt % and the ceramic inhibitor powder of 5 to 30 wt % when each of the metal powder, the organic vehicle, and the ceramic inhibitor powder in which the nano glass added with the rare-earth element is mixed is prepared; manufacturing a secondary mixture by mixing the primary mixture of 50 to 70 wt % and the organic vehicle of 30 to 50 wt % when the primary mixture is manufactured; and manufacturing the metal paste for the internal electrode by filtering the secondary mixture when the secondary mixture is manufactured.
