PROBLEM TO BE SOLVED: To provide a ceramic electronic parts having uniform divided shape dimensions after baking with high production efficiency, by a method wherein a metallic die having the ceiling surface of a protruding part in mesa shape is adopted to form a groove by pressing down the metallic die having the protrusions on a ceramic green sheet surface. SOLUTION: After forming a separating groove by pressing down a metallic die to the surface of a ceramic green sheet 1, the ceramic green sheet 1 is baked. Next, in the step of dividing the green sheet 1 into individual pieces along the separating groove after the formation of an electrode on the surface of the green sheet 1, a metallic die 2 having mesa-shaped protrusions 3 in lattice is used to form the separating groove. Through these procedures, the inverse mesa-shaped separating grooves are formed on the surface of the sheet 1 so that the bottom parts 6 of the separating grooves 1a are made denser than other parts by the pressurization. Accordingly, when the force to divide green sheet into individual pieces is applied after the baking step the stress is concentrated along the interface between the denser part and other parts, so that the individual pieces may be cleanly divided, at the interface thereby manufacturing the individual pieces having uniform shape dimensions. |
