Abstract
A laminated ceramic capacitor having a laminated body composed of a plurality of ceramic layers for inner layers; a plurality of internal electrodes at the interfaces between the plurality of ceramic layers for inner layers; and a plurality of ceramic layers for outer layers, provided on the top and bottom so as to sandwich the plurality of ceramic layers for inner layers. The ceramic layers for inner layers are composed of a material containing a multiple oxide including an alkaline-earth metal. The ceramic layers for outer layers respectively have TiO2 ceramic layers containing TiO2 as their main constituent for certain layers including the outermost layers, and multiple oxide ceramic layers containing a multiple oxide including an alkaline-earth metal for the other layers.
