内容: | To provide a ceramic electronic component capable of lowering the rate of defective insulation resistance, even with a thin dielectric layer composing the ceramic electronic component, wherein capacitance temperature characteristics satisfy X6S characteristics (from -55 to 105°C, ΔC/C=±22%) specified in EIA standards. ! The ceramic electronic component contains the dielectric layer, wherein the dielectric layer contains an essential component containing a dielectric oxide of a composition represented by the formula: {(Sr1-xCax)O}m×(Ti1-yZry)O2 (wherein m, x and y representing the compositional molar ratios satisfy the relations: 1.005≤m<1.1, 0≤x≤1.0 and 0≤y≤0.4, respectively) and a first subsidiary component containing MbO and/or Al2O3. The proportion of the first subsidiary component to the essential component is 0.05-3 mol calculated in terms of MgO or Al2O3 based on 100 mol essential component. ! (C)2007,JPO&INPIT |
