Abstract
A dielectric ceramic capacitor that has excellent reliability and particularly excellent life characteristics in a load test even when the thickness of a dielectric ceramic layer is reduced uses a dielectric ceramic as a dielectric ceramic layer in a laminated ceramic capacitor which is a substance containing, as the main component, (Ba, R)(Ti, V)O3 or (Ba, Ca, R)(Ti, V)O3 in which R is at least one selected from La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, and Y, and in which both V and R are present uniformly in the main component particles.
Claims20
A dielectric ceramic, comprising, as the main component, (Ba, R)(Ti, V)O3 optionally containing Ca in the (Ba, R) site, in which R is at least one member of the group selected from the group consisting of La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, and Y.
