Multilayer ceramic electronic device and dielectric ceramic composition

Abstract

A multilayer ceramic electronic device includes a dielectric layer of which a main component is a dielectric ceramic composition represented by a formula (BiaNabMc)(TidNbeNf)O3, where M is at least one element selected from La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Yb, Y, Bi, Ba, Sr, Mg, and Ca, and N is at least one element selected from Mn, V, Fe, W, and Mo, and where following conditions 0.1<a<0.5, 0.4<b<0.8, 0<c≤0.2, 0.4<d<0.8, 0.2<e<0.5, 0<f≤0.1, 0.90≤a+b+c≤1.05 and 0.90≤d+e+f≤1.05 are satisfied, a plurality of internal electrode layers sandwiching the dielectric layer and facing each other, and a plurality of external electrodes, each of which is electrically connected to teach of the plurality of internal electrode layers.
