PURPOSE : A dielectric composition is provided to include a first minor component, a second minor component, a third minor component, and a forth minor component in a specific ratio, thereby realizing an MLCC(Multi-Layered Ceramic Capacitor) without making a thin dielectric layer.CONSTITUTION : A dielectric composition comprises a ceramic body(110) laminated with multiple dielectric layers, an inner electrode, and an outer electrode(120a, 120b). A dielectric composition comprising the dielectric layers comprises a base metal powder, a first minor component, a second minor component, a third minor component, and a forth minor component. The first minor component comprises a content(x1) of 0.01-1.0at% of carbonate or an oxide containing a transition metal to 100mole of the base metal powder. The second minor component comprises a content(y) of 0.01-3.0at% of carbonate or an oxide containing a fixed valence acceptor element to 100mole of the base metal powder. The third minor component comprises carbonate or an oxide containing a Ce element(content = z at%) and at least one rare-earth material(content = w at%). The forth minor component comprises a sintering gradient material. For 100 mole of the base metal powder, 0.01 COPYRIGHT KIPO 2013 |
