PROBLEM TO BE SOLVED : To obtain a porcelain of dielectrics and its production process capable of enhancing specific dielectric constant, and to provide a laminated ceramic condenser capable of enhancing capacitance without thinning layer of dielectrics to achieve high fidelity. SOLUTION : This porcelain of dielectrics comprises BaTiO3, as the main component, Mg, Mn and rare earth elements having specific dielectric constant at 25 deg.C of 4300 or more. Variation in specific dielectric constant in the range of -25 to 85 deg.C based on that at 20 deg.C is within ±15%. |
