Zusammenfassung:	PURPOSE:To obtain a porcelain composition represented by a specific formula and improved in its dielectric constant by sintering a molded raw material in an oxygen-containing atmosphere. CONSTITUTION:BaCO3, Nd2O3, TiO2, Bi2O3, etc., as raw materials are. mixed with each other in a prescribed ratio in a wet state, dried, calcined at 1000-1200 deg.C, and further ground in a wet state. The produced slurry is dried, mixed with an organic binder, granulated, press-molded, and subsequently sintered in an oxygen-containing atmosphere to produce a dielectric material porcelain composition having a composition represented by E formula: xBaO.yNd2O3.zTiO2.vBi2O3 (0.130
