A laminated ceramic capacitor that includes a ceramic laminated body having a stacked plurality of ceramic dielectric layers and a plurality of internal electrodes opposed to each other with the ceramic dielectric layers interposed therebetween, and external electrodes on the outer surface of the ceramic laminated body and electrically connected to the internal electrodes. The internal electrodes contain Ni and Sn, a proportion of the Sn/(Ni+Sn) ratio is 0.001 or more in molar ratio is 75% or more in a region of the internal electrode at a depth of 20 nm from a surface opposed to the ceramic dielectric layer, and the proportion of the Sn/(Ni+Sn) ratio is 0.001 or more in molar ratio is less than 40% in a central region in a thickness direction of the internal electrode.
