摘要：
A dielectric ceramic body prepared by firing a mixture of a cordierite glass powder and a TiO.sub.2 powder, or a mixture of these powders and a RE.sub.2 Ti.sub.2 O.sub.7 powder (RE representing a rare earth element), wherein particles of the Ti.sub.2 powder or particles of Ti.sub.2 powder and the RE.sub.2 Ti.sub.2 O.sub.7 powder are dispersed in a matrix phase of crystalline cordierite produced from the fired cordierite glass powder. In the first case, the cordierite glass powder and the Ti.sub.2 powder have a proportion which satisfies 70.ltoreq.x
