PURPOSE:To aim at reduction in electrode cost with the promotion of large capacity in a laminated condenser by containing a specific amount of Mn, SiO2 and ZnO each in a main component to be expressed in a formula (Sr1-xCax)m(Ti1-yZry) as a subcomponent. CONSTITUTION:A main component is expressed with a formula (Sr1-xCax)m(Ti1-yZry), and x, y and m are of 0.30<=x<=0.50, 0.92<=y<=0.98, 0.95<=m<=1.08, respectively. And Mn is converted into MnO2 and its 0.01-4pts.wt., a 2.00-8pts. wt. of SiO2 and 0.01-1.00pts.wt. of Zn are contained in this main component 100pts.wt. as a subcomponent. A nonreducible dielectric ceramic constituent of suchlike composition is used as material for a laminated condenser, and what is more, a base metal such as Ni, Fe, Cr or the like is usable as an internal electrode, so that reduction in cost of the electrode with the promotion of large capacity in the laminated condenser can be realized. |
