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 relationship of (concentration of the element acting as a donor)×(valence of the element acting as a donor−4)<(concentration of the element acting as an acceptor)×(4−valence of the element acting as an acceptor) is satisfied, in a center region of each grain of the ceramic raw material powder, wherein a relationship of (concentration of the element acting as a donor)×(valence of the element acting as a donor−4)>(concentration of the element acting as an acceptor)×(4−valence of the element acting as an acceptor) is satisfied, in a circumference region of each grain of the ceramic raw material powder.
