Abstract
A laminated ceramic capacitor includes a capacitor body of alternately stacked dielectric layers and internal electrode layers, and an external electrode provided on the end face of the capacitor body on which the internal electrode layer is exposed. The dielectric layer has a crystal phase composed mainly of barium titanate and having a cubic system crystal structure. The grain diameter of crystal grains constituting the crystal phase is 0.05 to 0.2 pm. The dielectric layer is formed of a ceramic containing, per mole of barium, 0.0014 to 0.03 moles yttrium, 0.0002 to 0.045 moles manganese, 0.0075 to 0.04 moles magnesium and 0.025 to 0.18 moles ytterbium. The dielectric bonding material is formed of a ceramic containing the same components as those of the main crystal phase of the dielectric ceramic constituting the dielectric layer.
