(1.0≤y≤15.0) are mixed to 100 pts.wt. of the material consisting of a perovskite type crystal phase expressed by the general formula of CaTiO 3 as the main crystals. The glass is expressed by the compositional formula of aB 2 O 3 -bBi 2 O 3 - cZnO, wherein a, b, and c satisfiy, by molar ratio, 0.2≤a≤0.5, 0.1≤b≤0.4, and 0.1≤c≤0.4; but, a+b+c=1. By the addition of small quantities of the above glass and B 2 O 3 , dense dielectric porcelain having the characteristics of a relative dielectric constant εr=50 to 150, and Q=300 to 820 (in the frequency of 4.2 to 6.7 GHz) can be heated and fired in the range of 890 to 920°C.
