Conductive paste composition for internal electrodes of multilayer ceramic capacitors, its manufacturing method, and conductive paste

摘要

PROBLEM TO BE SOLVED: To suppress oversintering of a conductive paste, suppress electrode interruption during sintering, and increase the coverage of an internal electrode layer after sintering. SOLUTION: The average particle size in the particle size distribution based on the number in the area circle equivalent diameter (Heywood diameter) obtained by image processing the imaging of the conductive powder with a scanning electron microscope (SEM) is 0. The ratio of the average particle size of the ceramic powder to the average particle size of the conductive powder is 0.1 or more and less than 0.3, and the content of the ceramic powder is the conductive powder. And a conductive paste composition which is 5.5% by mass or more and 13% by mass or less with respect to the total mass of the ceramic powder is provided. [Selection diagram] Fig. 1
