摘要： A dielectric composition includes a base main component including Ba and Ti and an accessory component, wherein a ratio of domain width/grain size of the dielectric composition is in the range of 0 to 0.2, a multilayer ceramic capacitor using the same, and a method for manufacturing a multilayer ceramic capacitor. It is possible to provide a dielectric composition that can implement a higher dielectric constant and good high temperature withstand voltage characteristics in the same grain size condition. It is expected that this effect can be effectively applied to the development of ultra high capacity MLCCs having a thin dielectric by implementing the same capacity while increasing the thickness of the dielectric than the case of applying the conventional dielectric material.
