The invention provides a multilayer ceramic capacitor. The multilayer ceramic capacitor includes: a multilayer structure in which each of a plurality of ceramic dielectric layers and each of a plurality of internal electrode layers are alternately stacked wherein: a concentration of a rare earth element of at least one of an end margin region and a side margin region is lower than that of a capacity region; a total concentration of Si and B of the at least one of the end margin region and the side margin region is higher than that of the capacity region. 本申请提供种多层陶瓷电容器，其包括：多层结构，其中多个陶瓷电介质层中的每个与多个内部电极层中的每个交替地堆叠，其中：端部边缘区域和侧部边缘区域中的至少个的稀土元素的浓度低于容量区域的稀土元素的浓度；端部边缘区域和侧部边缘区域中的上述至少个的Si和B的总浓度高于容量区域的Si和B的总浓度。
