PURPOSE: To reduce the cost without deteriorating the characteristic by using a specified unreducing dielectric porcelain as dielectric material and base metal represented by nickel, etc., as internal electrode material.
CONSTITUTION: One hundred parts by weight of a main component made up of BaTiO3 at 95.0-98.0mol.% where a content of unreacted BaO is 0.7wt.% and Ba/Ti molar ratio is 1.005-1.025 and at least one kind of rare earth oxide at 2.0-5.0mol.% selected from La, Nd, Sm, Dy and Er, and 0.3-1.5 parts by weight of MnO as a by-component and 0.5-2.5 parts by weight of glass oxide where BaO-SrO-Li2O--SiO2 is a main component are contained. In this case, firing is possible without being semiconductorized even under hypoxia partial pressure. If this unreducing dielectric porcelain composition is used, therefore, base metal can be used as internal electrode material. It is thereby possible to reduce the cost of a laminated ceramic capacitor.
