The present invention provides a dielectric ceramic composition, a capacitor using the composition and the producing method, of having a lower dielectric loss and a stable characteristics in high frequency bandwidth, and enabling to use a base metal or a carbon-based material as an electrode material by allowing sintering at a low temperature, thereby resulting in lower cost. The dielectric ceramic composition according to present invention, is characterized in comprising a main component of formula Sr Mg (Xr Ti ) O (where 0.8&lE;x&lE;1; 0.9&lE;y&lE;1) to which MnO of 0.05-15 wt %, at least one of 0.001-5 wt % selected from the group consisting of Bi O , PbO and Sb O and a glass component of 0.5-15 wt % are added based on the weight of the main component.
