A dielectric glass-ceramic composition comprises a BaO-TiO<SB>2</SB>-ReO<SB>3/2</SB>-based ceramic composition represented by the formula xBaO-yTiO<SB>2</SB>-zReO<SB>3/2</SB> wherein 8 & x & 18, 52.5 & y & 65, 20 & z & 40 hold, in which x, y, and z are mole percent, <F>x + y + z = 100</F>, and Re indicates a rare earth element, and glass composition comprising 10 to 25 wt% of SiO<SB>2</SB>, 10 to 40 wt% of B<SB>2</SB>O<SB>3</SB>, 25 to 55 wt% of MgO, 0 to 20 wt% of ZnO, 0 to 15 wt% of Al<SB>2</SB>O<SB>3</SB>, 0.5 to 10 wt% of Li<SB>2</SB>O, and 0 to 10 wt% of RO in which R is Ba, Sr, and/or Ca. The dielectric composition may also contain CuO and TiO<SB>2</SB> as separate components. |
