A dielectric composition that can be fired at a temperature of below 900° C. The dielectric composition has a dielectric constant of 25-35 and a quality factor (Qxf) of 6,000-20,000 GHz. The composition comprises 3-16 wt % of K<SUB>2</SUB>O-Na<SUB>2</SUB>O-Li<SUB>2</SUB>O-B<SUB>2</SUB>O<SUB>3</SUB>-SiO<SUB>2 </SUB>system glass frit and 84-97 wt % of BaO-TiO<SUB>2 </SUB>system dielectric ceramics. The composition can be effectively applied to construct a part of a ceramic multi-layer packaging as a resonator form such as a filter or an antenna, etc.
