Abstract
A dielectric ceramic composition enabling one to obtain a laminated capacitor which hardly causes degradation of insulation resistance with time under high-humidity even in using a base metal such as Ni as an internal electrode, contains as a main constituent, a constituent represented by (CaSr)(TiZr)Oin which x and y are 0≦x≦1 and 0≦y≦0.50, and, as accessory constituents, at least 0.5 parts by mol and at most 15 parts by mol of SiO, at least 0.1 parts by mol and at most 10 parts by mol of MnO, and at least 0.01 parts by mol and at most 0.079 parts by mol of AlO, with respect to 100 parts by mol of the main constituent.
