ABSTRACT:
A ceramic green sheet having good surface roughness and few pinhole defects even when producing a thin ceramic green sheet is stably produced, to permit efficiently and securely manufacturing a multilayer ceramic electronic part in which deterioration of its life due to unevenness of interfaces between internal electrodes and ceramic layers and the occurrence of structural defects, such as delamination, bending of an electrode portion, etc, in a multilayer thin film to be suppressed. A dry sheet obtained by forming ceramic slurry to a sheet on a carrier film is smoothed by pressing using a plate press, a hydrostatic press or a calender roll under predetermined temperature and pressure conditions to improve the surface smoothness of the ceramic green sheet independently of the particle diameter of the ceramic and its dispersibility. An electrode paste is coated in a predetermine pattern on the thus-produced ceramic green sheet to form a sheet provided with an electrode. A plurality of the sheets provided with electrodes are laminated, and the burned to produce a multilayer ceramic electronic part.
