This dielectric material is a glass ceramic containing strontium anorthite (SrAl.sub.2 Si.sub.2 O.sub.8) as the main crystalline phase, and may contain the TiO.sub.2, which remains unchanged after sintering. The absolute value of the temperature coefficient of resonance frequency of the dielectric material is 20 ppm/.degree. C. or lower, preferably 10 ppm/.degree. C. or lower, more preferably 5 ppm/.degree. C. or lower. The product of the unloaded quality coefficient and resonance frequency is 1,800 GHz or larger, preferably 2,500 GHz or larger. This material therefore has excellent dielectric properties.

    摘要： A low-temperature firing ceramic composition contains Sr2MgSi2O7 crystals forming a major crystal phase of the composition. This composition can be produced, for example, by a process including the steps of (a) mixing together a silica powder, a magnesia powder and a strontium oxide powder to obtain a powder mixture; (b) subjecting the powder mixture to a calcination at a temperature of 1,000-1,200° C. to obtain a calcination product containing Sr2MgSi2O7 crystals; (c) mixing the calcination product with alumina powder, boron oxide powder, lithium oxide powder, binder and ethanol to obtain a powder mixture; (d) granulating the powder mixture; (e) shaping the resulting granules into a green body; (f) compacting the green body by a hydrostatic pressing (CIP); and (g) firing the resulting compact in an atmosphere of air, thereby obtaining the composition. A wiring substrate includes a laminate of green sheets, each containing Sr2MgSi2O7 crystals, and a wiring pattern formed in an inside of the laminate and/or on a surface of the laminate.
