ABSTRACT:
In order to manufacture a ceramic layered product for manufacturing a multilayer ceramic capacitor, a plurality of reels (23) are prepared, which are wound with a plurality of types of elongated mother ceramic sheets (12), each having a plurality of electrode patterns (14) and a plurality of registration marks (15) distributed along its longitudinal direction. The mother ceramic sheets (12) are drawn out from the respective reels (23) onto related sheet cutting stages. Regions including the electrode patterns (14) are punched from respective ones of the mother ceramic sheets (12) provided on a selected sheet cutting stage (25) by a cutting head (52) whose periphery is enclosed with a cutting edge (51) on the basis of the registration marks. Then the ceramic sheets (35) punched out from the mother sheet by the cutting head (52) are carried to a stacking jig (34) by the cutting head (52) and stacked with each other on the stacking jig (34).
