In one inventive aspect, a multilayer ceramic capacitor is provided, in which occurrence of cracks can be prevented even when temperature of the capacitor itself is increased. Non-flat portions are formed in both sides in a width direction of each of inner electrode layers. In addition, the non-flat portions comprise regions substantially changed into oxide regions, therefore a thermal expansion coefficient of the non-flat portions can be decreased so that stress due to difference in thermal expansion coefficient to non-flat portions can be reduced, and the stress can be dispersed in accordance with curvature or inclination of the non-flat portions. That is, stress generated when temperature of the capacitor itself is increased is decreased and dispersed, thereby occurrence of cracks due to the stress can be prevented in side margins of the ceramic chip.
