摘要： 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 ABO3 type with a specified ionic radius in which a ratio of a six-coordinate ionic radius of an A-site element in ABO3 to 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 ABO3 type with the specified ionic radius is at least one of NiTiO3, MgTiO3, or MnTiO3.

摘要： An electronic component includes a first external electrode disposed on a first end surface and a second external electrode disposed on a second end surface. The first external electrode includes a first conductive layer including ceramic particles. The second external electrode includes a second conductive layer including ceramic particles. An end portion of a first internal electrode is located inside the first conductive layer. The electronic component includes little or no cracks and has a low equivalent series resistance (ESR).

摘要： 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 ABO3 type with a specified ionic radius in which a ratio of a six-coordinate ionic radius of an A-site element in ABO3 to a six-coordinate ionic radius of copper is about 0.96 or greater and about 1.04 or less.

摘要： A method to produce a multilayer ceramic electronic component includes forming supports by an ink jet printing method to produce a green multilayer ceramic capacitor. A green ceramic layer and outer electrodes of the multilayer ceramic electronic component are formed by the ink jet printing method while the supports define peripheries of the green ceramic layer and the outer electrodes. When fired, the green multilayer ceramic electronic component is converted to a sintered multilayer ceramic electronic component, and the supports disappear by heating.
