PROBLEM TO BE SOLVED: To provide a method for manufacturing a low temperature-baked ceramic composition from nonglass raw material that is compacted in temperature <=1,000 deg.C and shows a stable low dielectric constant and a low dielectric loss, and to provide a wiring board using the composition. SOLUTION: The ceramic composition mainly contains a diopsied crystal. An insulation layer for the wiring board preferably is provided with the properties: dielectric constantε<=7;Q×f value >=10,000 GHz. The composition preferably contains SiO2-like crystal, a wollastonite crystal and/or an enstatite crystal as a subsidiary crystal. |
