A low temperature sintering ceramic composition can be sintered at 850 to 1,000°C, and the sintered ceramic has a low dielectric constant (9 or less at 16 GHz or more) and a high Qf (10,000 or more). The composition can be co-sintered with wiring material containing Ag, Au, or Cu. The ceramic composition includes (by mass) CaO, MgO, and SiO2 in total: over 60% to 98. 6%; Bi2O3: from 1 % to under 35%; and Li2O: from 0. 4 % to under 6%; wherein (CaO+MgO) and SiO2 are contained in the molar ratio of from 1:1 to under 1:2.5. |
