Claim 31:
32. A manufacturing method of a ceramic electronic device comprising:
forming a ceramic multilayer structure by stacking a plurality of stack units, each of which has a structure in which an internal electrode pattern is formed on a dielectric green sheet including ceramic raw material powder having a perovskite structure expressed by a general formula ABO3, the ceramic raw material powder being subjected to a ball milling in acetic acid aqueous solution; and
firing the ceramic multilayer structure,
wherein a dispersion of atomic displacement amounts between B site atoms and oxygen atoms of a shell of a crystal grain having a core-shell structure included in a dielectric layer obtained from the dielectric green sheet is larger than a dispersion of atomic displacement amounts between B site atoms and oxygen atoms of a core of the core-shell structure.
