Abstract: A laminated ceramic capacitor includes a laminate including an inner layer portion including a ceramic dielectric layer and an internal electrode, and an outer layer portion defined by a ceramic dielectric layer. At both end portions of the laminate, external electrodes are connected to the internal electrode. In the outer layer portion, a glass layer is provided. An outer ceramic dielectric layer positioned outwardly of the glass layer has a different color from the color of an inner ceramic dielectric layer positioned inwardly of the glass layer.

Abstract: A multilayer ceramic capacitor includes a laminated body including dielectric layers and internal electrodes alternately laminated, and an external electrode provided on the surface of the laminated body and connected to the internal electrodes. The internal electrode includes a facing electrode portion facing another internal electrode with the dielectric layer provided therebetween, and an extended electrode portion extended from the facing electrode portion to the surface of the laminated body and connected to the external electrode. At least one layer of the internal electrodes includes a bent portion in the extended electrode portion. The distance between extended electrode portions adjacent to each other in the lamination direction narrows from the end portion of the facing electrode portion toward the bent portion, and widens from the bent portion toward the end portion of the extended electrode portion on the external electrode side.
