    摘要： A method for manufacturing a laminated ceramic electronic component allows for production of highly reliable laminated ceramic electronic components even when the coating rate of a ceramic slurry on a surface of a carrier film is increased in order to reduce the thickness of the ceramic green sheet. A ceramic green sheet is formed by pulling out a carrier film from a carrier film roll, coating the film with a ceramic slurry using a coating apparatus, drying the film with a drying apparatus, and rolling up the film using a take-up apparatus. The carrier film is unrolled, an internal electrode pattern is printed thereon by a printing apparatus, the surface of the film is dried, and the film is rolled up by the take-up apparatus. The rolled carrier film is pulled out, the ceramic green sheet is peeled away, and a plurality of the ceramic green sheets are laminated. Following the cutting of the laminated body into individual elements, these elements are fired, and external electrodes are formed thereon. In this manufacturing process, a film used as the carrier film is such that Rmax of the ceramic slurry coated surface is about 0.2 &mgr;m or less, and Rmax of the opposite surface thereof is about 0.5 &mgr;m to 1.0 &mgr;m.
