    摘要: The invention intends to provide a dielectric porcelain composition for use in electronic devices, which has the dielectric characteristics such that the Qf value is high, the temperature coefficient τf of a resonant frequency is small and a value thereof can be controlled in a wide range in positive and negative directions in the vicinity where the relative dielectric constant ∈r is 39. According to the invention, when, in La—Pr—Al—Ga—Sr—Ti-based oxide dielectric porcelain, contents of the respective elements are limited to be within particular ranges and Sr is partially substituted by Ca, a structure having a (1-x)(La1-yLny)(Al1-zGaz)O3-x(Sr1-mCam)TiO3 solid solution as a main phase, in which a solid solution of Al—Ga—Sr-based oxide and/or a solid solution of Al—Ga-based oxide and a Sr oxide is/are precipitated in a grain boundary thereof, can be obtained, whereby the above-mentioned object can be achieved.
