Abstract
Provided is a highly reliable laminated ceramic capacitor in which decrease of dielectric constant under a high electric field is small and which satisfies the B-grade and X7R grade characteristics, using Ni for the inner electrodes, wherein the dielectric material contains about 0.2 to 5.0 parts by weight of Li,O—(Si, Ti),—MO oxides (MO is at least one of the compounds of Al,O,and ZrO,) or SiO,—TiO,—XO oxides (XO is at least one of the compounds of BaO, CaO, SrO, MgO, ZnO and MnO) relative to 100 parts by weight of a principal component represented by (Ba,Ca,O),TiO,+&agr;Re,O,+&bgr;MgO+&ggr;MnO (Re,O,represents at least one of Y,O,, Gd,O,, Tb,O,, Dy,O,, Ho,O,, Er,O,and Yb,O,).
