CERAMIC RAW MATERIAL POWDER, MULTILAYER CERAMIC CAPACITOR AND MANUFACTURING METHOD OF MULTILAYER CERAMIC CAPACITOR
Ceramic raw material powder includes: a main phase having a perovskite structure, wherein elements acting as a donor and an acceptor are solid-solved in B sites of the perovskite structure, wherein a first relationship of value Avalue B is satisfied in a circumference region of each grain of the ceramic raw material powder, and value A in the second relationship gradually decreases from the circumference region to the center, wherein value A is a value of (concentration of the element acting as a donor)×(valence of the element acting as a donor−4), and value B is a value of (concentration of the element acting as an acceptor)×(4−valence of the element acting as an acceptor).
