Abstract:
A laminated ceramic capacitor which provides favorable life characteristics, even when a high electric field strength is applied while dielectric ceramic layers are reduced in layer thickness to less than 1 μm, contains a dielectric ceramic a compound represented by: (Ba1-x/100Cax/100)mTiO3 (0≦x≦20) as its main constituent, and as its accessory constituent, aMg-bSi-cMn-dR (R is at least one of La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, and Y, and a, b, c, and d (part by mol) respectively satisfy the conditions of 0.1
