PROBLEM TO BE SOLVED: To provide a multilayer ceramic electronic component further improved in high-temperature load life and relative permittivity. A multilayer ceramic electronic component having a laminate in which internal electrode layers and dielectric layers are alternately laminated, The dielectric layer is composed of a dielectric ceramic composition including a main component represented by a general formula ABO 3 (A is Ba or the like, B is Ti or the like), and a rare earth component R; In the dielectric layer, there is a segregation phase containing the rare earth component R, In the cross-section observation in the stacking direction, the area ratio of the segregated phase is 104 ppm to 961 ppm, A multilayer ceramic electronic component in which 96% or more of the total area of the segregated phases is in contact with the internal electrode layer.
