    摘要： A multi-layer capacitor including a capacitor body including dielectric layers, and first and second internal electrode layers which are alternately laminated by mediation of the dielectric layers. The laminate of the first and second internal electrode layers and the dielectric layers are co-fired. The capacitor body further includes first and second electrode terminals formed on one main surface of the capacitor body. At least a single first via electrode extends through the capacitor body in the lamination direction of the capacitor body so as to connect the first electrode terminal and the first internal electrode layers, and at least a single second via electrode extends through the capacitor body in the lamination direction of the capacitor body so as to connect the second electrode terminal and the second internal electrode layers. The via electrodes have an aspect ratio of 4 to 30 as measured after firing.

    摘要： A laminated ceramic capacitor (10) divided into a first laminate (11), a second laminate (12), a third laminate (13), and a fourth laminate (14). The first laminate (11) includes a ceramic layer (15) serving as a dielectric layer. The ceramic layer (15) is thicker than a ceramic layer (17) sandwiched between internal electrodes (16a) in the second laminate (12) or the fourth laminate (14), and thinner than 20 times the thickness of the ceramic layer (17). The third laminate (13) includes dielectric layers, which serve as the ceramic layers (17), and has a thickness of 5% of the total thickness of the second laminate (12) and the fourth laminate (14). Accordingly, the third laminate (13) achieves the function of absorbing an electrode-induced thickness differential. Also, by means of regulating the thickness of the first laminate (11), portions of via electrodes (18) that extend without being electrically connected to the internal electrodes (16b) can be shortened.
