摘要： There is provided a multilayer ceramic capacitor. The capacitor includes: a multilayer body having a dielectric layer; and first and second internal electrodes disposed in the multilayer body, the dielectric layer being disposed between the first and second internal electrodes, wherein, in a cross-section taken in a width-thickness direction of the multilayer body, an offset portion is defined as a portion where adjacent first and second internal electrodes do not overlap with each other, and a ratio (t1/td) of a width t1 of the offset portion to a thickness td of the dielectric layer is 1 to 10.
