摘要： 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.

摘要翻译：在一个创造性方面，提供了一种多层陶瓷电容器，其中即使当电容器本身的温度升高时也可以防止出现裂缝。在每个内电极层的宽度方向的两侧形成非平坦部。此外，非平坦部分包括基本上变为氧化物区域的区域，因此可以减小非平坦部分的热膨胀系数，从而可以减少由于与非平坦部分的热膨胀系数的差异引起的应力，以及应力可以根据非平坦部分的曲率或倾斜度而分散。也就是说，当电容器本身的温度升高时产生的应力减小并分散，从而可以防止在陶瓷芯片的侧边缘中由于应力而产生裂缝。
