The present invention relates to a dielectric composition and a multi-layered ceramic electronic part using the same. Provided in the present invention is a dielectric composition which comprises a dielectric grain with a perovskite structure represented by ABO3, the dielectric grain comprises a base material which has at least one element of the rare-earth elements (RE) applied to at least one among the A and B elements and transition elements (TR), and the ratio of the transition element for the rear-earth element (TR/RE) is 0.2-0.8.COPYRIGHT KIPO 2014
