ABSTRACT:
There is provided a dielectric ceramic material in which the firing temperature dependency of the relative dielectric constant can be suppressed and the mechanical strength can be improved. Specifically, there is provided a dielectric ceramic material including: main constituents given by a composition located in the region, in a ternary diagram of ZrO2, SnO2and TiO2shown in FIG.1, bounded by point A, point B, point C, point D, point E and point F; and ZnO: 0.5 to 5 wt %, NiO: 0.1 to 3 wt %, and SiO2: 0.008 to 1.5 wt % in relation to the total weight of the main constituents. The dielectric ceramic material can include Nb2O5: 0.2 wt % or less and K2O: 0.035 wt % or less in relation to the total weight of the main constituents.
