| 简介 |
The present invention is provided with : a capacitor body 1 obtained by alternately stacking a plurality of dielectric layers 5 and internal electrode layers 7; and an external electrode 3 provided to an end surface on which the internal electrode layer 7 of the capacitor body 1 is exposed. The dielectric layers 5 comprise a dielectric porcelain composed of crystal particles 9 having barium titanate as a main component and containing a rare earth element therein, and the crystal particles 9 have in a particle boundary vicinity 9a a low concentration region 12 in which the concentration of the rare earth element is lower than the inside 9b thereof. The crystal particles further contain vanadium, and the low concentration region 12 contains more of the vanadium than the inside 9b. The crystal particles 9 further contain magnesium and manganese, and the magnesium and the manganese have a concentration gradient that is at a maximum at the particle boundary vicinity 12 and lowers toward the inside 9b. |
