Multilayer ceramic electronic component
The object of the present invention is to provide a multilayer ceramic electronic component having improved highly accelerated lifetime and specific permittivity. A multilayer ceramic electronic component comprising a multilayer body in which an internal electrode layer and a dielectric layer are stacked in alternating manner, wherein the dielectric layer comprises a dielectric ceramic composition having a main component expressed by a general formula ABO3 (A is Ba and the like, and B is Ti and the like) and a rare earth component R, a segregation phase including the rare earth component R exists in the dielectric layer, an area ratio of the segregation phases in a cross section along a stacking direction is 104 ppm to 961 ppm, and 96% or more of a total area of the segregation phases contact with the internal electrode layer.
