Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a dielectric porcelain, having a high relative permittivity and a high value of Q and further a low rate of change in resonance frequency for a temperature change by providing the dielectric porcelain with a composition of a perovskite compound and Bi at a molar ratio within a prescribed range. SOLUTION: This dielectric porcelain is produced by preparing a perovskite compound represented by the formula (a), (b), (c), (d), (e) and (f) are each the molar ratio of each element in the perovskite compound; 0
