<p>Disclosed is a laminated ceramic capacitor that comprises a capacitor body (1) comprising alternately stacked dielectric layers (5) and internal electrode layers (7), and an external electrode (3) provided on the end face of the capacitor body (1) on which the internal electrode layer (7) is exposed. The dielectric layers (5, 5) disposed on both respective sides of the internal electrode layer (7) held between the dielectric layers (5, 5) are formed integrally with a dielectric bonding material (8) disposed so as to extend through a part of the internal electrode layer (7). The dielectric layer (5) has a crystal phase, composed mainly of barium titanate, as a main crystal phase. The crystal phase has a crystal structure based on a cubic system. The average grain diameter of crystal grains constituting the crystal phase is 0.05 to 0.2 µm. The dielectric layer (5) is formed of a dielectric ceramic containing yttrium, manganese, magnesium, and ytterbium. The dielectric bonding material (8) is formed of a dielectric ceramic containing the same components as the components of the main crystal phase of the dielectric ceramic constituting the dielectric layer (5).</p> |
