<p>Provided is a laminated ceramic capacitor which produces excellent lifetime characteristics in a high-temperature loading test even when dielectric layers are reduced in thickness. The dielectric ceramic contains, as its main constituent, a compound represented by the general formula (Ba1-x-yCaxRey)(Ti1-zMz)O3 (where Re is at least one or more elements selected from among La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, and Y, and M is at least one or more elements selected from among Mg, Mn, Al, Cr, and Zn), 0≰x≰0.2, 0.002≰y≰0.1, and 0.001≰z≰0.05. This dielectric ceramic has crystal grains of 20 nm or more and 150 nm or less in average grain size.</p> |
