内容: Disclosed is a dielectric ceramic material used for a multilayer ceramic capacitor, namely a dielectric ceramic composition having a high resistivity which can be fired together with an internal electrode mainly composed of Ni at a temperature not more than 1200 DEG C. This dielectric ceramic composition mainly contains a tungsten bronze type complex oxide represented by the chemical composition: (K1-xNax)Sr2Nb5O15 (wherein 0 = x < 0.2), while containing, as minor components, 0.05-20 parts by mole of R (R is at least one element selected from the group consisting of Y, La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu) and 0.05-40 parts by mole of M (M is at least one element selected from the group consisting of Mn, V, Li, Si, Ni, Cr, Co, Fe, Zn, Mg and Zr) per 100 parts by mole of the main component.
