Abstract:
1. A laminated ceramic capacitor, comprising: a laminate block made of alternately stacked ceramic dielectric layers and internal electrodes and having a top and bottom with respect to the stacking direction, two side faces opposite to each other from which layers of the internal electrodes are exposed, and a front and rear from which layers of the internal electrodes are exposed; a pair of cover layers placed on the top and bottom of the laminate block; ceramic bodies formed on both side faces of the laminate block; and a pair of external electrodes that are electrically connected to the internal electrodes at the front and rear of the laminate block, wherein the average grain size of ceramic dielectric grains constituting the ceramic bodies is smaller than the average grain size of ceramic dielectric grains constituting the ceramic dielectric layers in the laminate block, wherein the average grain size of ceramic dielectric grains constituting the cover layers is smaller than the average grain size of ceramic dielectric grains constituting the ceramic dielectric layers, but larger than the average grain size of ceramic dielectric grains constituting the ceramic bodies.
