Abstract
A conductive paste included in inner electrodes of a multilayer ceramic capacitor is fired and includes a conductive metal powder, a ceramic powder, an organic solvent, and an organic binder. The conductive metal powder includes copper, and at least a portion of the ceramic powder is a powder of at least one oxide of an ABOtype with a specified ionic radius in which a ratio of a six-coordinate ionic radius of an A-site element in ABOto a six-coordinate ionic radius of copper is about 0.96 or greater and about 1.04 or less.
