Provided is a multilayer ceramic capacitor having a capacitor body formed by alternately laminating a dielectric layer and an internal electrode layer, and an external electrode formed on both ends of the capacitor body. The dielectric layer has at least two type of barium titanate crystal grains that differ from one another in at least one selected from Ca composition concentration, Sr composition concentration, and Zr composition concentration, and a grain boundary phase. If this multilayer ceramic capacitor employs, as a dielectric layer, a dielectric ceramic that contains barium titanate crystal grains in which part of Ba is substituted by Ca, Sr, or Zr, it is capable of suppressing the grain growth of crystal grains, and improving relative dielectric constant, temperature characteristic, and high-temperature load test characteristic, for example, in high-volume manufacturing using a tunnel type large kiln.
