Abstract
A monolithic ceramic electronic component includes a laminate including a plurality of ceramic layers obtained by sintering a ceramic raw material powder, and a plurality of internal electrodes located between the ceramic layers and obtained by sintering a metallic powder. The ceramic layers have a thickness of about 3 .mu.m or less and are composed of ceramic grains having an average particle diameter of more than about 0.5 .mu.m, the particle diameter of the ceramic grains in the thickness direction of the ceramic layers is smaller than the thickness of the ceramic layers, and the internal electrodes have a thickness of about 0.2 to 0.7 .mu.m. Preferably, the monolithic ceramic electronic component further includes an external electrode formed on each of the opposing ends of the laminate, the ceramic layers are composed of a ceramic dielectric material, and each of the plurality of internal electrodes is formed with an edge being exposed to either one of the opposing ends of the laminate so as to be electrically connected to either one of the external electrodes to form a monolithic ceramic capacitor.
