| 内容： | To provide a laminated ceramic capacitor capable of performing low temperature sintering and also satisfying a low specific dielectric constant and a prescribed temperature coefficient of capacitance, capable of easily being multilayered without causing a structural defect even when a small-sized low capacity laminated electronic component is designed, capable of suppressing the reduction of an equivalent series resistance and the variation of an electrostatic capacity and having excellent high-temperature load reliability. ! A dielectric ceramic composition is expressed by the general formula: (1-a)MgzSiO2+z+a(Sr1-xCax)w(Ti1-yZry)O2+w. In the general formula, x, y and a satisfy relations of 0≤x≤0.2, 0.01≤y≤0.40, 1.70≤z≤1.99, 0.98≤w≤1.02 and 0.05≤a≤0.77 respectively. ! (C)2007,JPO&INPIT |
