Abstract

A conductive paste defining inner electrodes of a multilayer ceramic capacitor manufactured through a firing step, includes a conductive metal powder, a ceramic powder, an organic solvent, and an organic binder. At least a portion of the ceramic powder is a powder of at least one oxide of 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 a metal element in the conductive metal powder is about 0.97 or greater and about 1.04 or less. Preferably, when the conductive metal powder includes nickel, the at least one oxide of ABOtype with the specified ionic radius is at least one of NiTiO, MgTiO, or MnTiO.
