A dielectric ceramic compact is provided which can be obtained by sintering at a low temperature of 1000° C. or less, can be obtained by co-sintering a dielectric ceramic composition with a metal having superior electrical conductivity, such as Ag, and has a high relative dielectric constant, a high Q and a small temperature coefficient of dielectric properties. The dielectric ceramic composition combines an xBaO-yTiO2-zReO3/2 ceramic composition and a glass composition; wherein 8<=x<=18, 52.5<=y<=65, 20<=z<=40, in which x, y, and z represent mole percent, x+y+z=100 and Re indicates a rare earth element, and the glass composition comprises about 10 to 25 wt % of SiO2, about 10 to 40 wt % of B2O3, about 25 to 55 wt % of MgO, 0 to about 20 wt % of ZnO, 0 to about 15 wt % of Al2O3, about 0.5 to 10 wt % of Li2O and 0 to about 10 wt % of RO in which R is at least one selected from the group consisting of Ba, Sr and Ca. |
