| 内容： | This invention provides a dielectric ceramic composed mainly of a compound represented by general formula: (Ba1-tCat)m(Ti1-u-xZruCux)O3 wherein 0.96 = m = 1.02, 0.001 = x = 0.03, 0 = t = 0.1 and 0 = u = 0.06. A specific rare earth element Re such as Dy, a specific metal element M such as Mn, and, further, Mg and Si are contained. The Cu is present in a homogeneously dispersed state in main phase particles constituting the main component. The content of each auxiliary component based on 100 parts by mole of the main component is Re: 0.1 to 1.5 parts by mole, M: 0.1 to 0.6 part by mole, Mg: 0.1 to 1.5 parts by mole, and Si: 0.1 to 2.0 parts by mole. The above constitution can realize a laminated ceramic capacitor that has high permittivity, has good temperature properties, is highly reliable, and causes no significant change in electrostatic capacitance with the elapse of time. |
