1. A method of manufacturing a cut-out sintered ceramic sheet, the method comprising:
a first step of obtaining a formed ceramic green sheet by forming the ceramic green sheet; a second step of obtaining a sintered ceramic sheet by sintering the formed ceramic green sheet; a third step of obtaining a film-adhered ceramic sheet by adhering a plastic resin film onto which adhesive is applied on at least one surface of the sintered ceramic sheet; and a fourth step of shearing the film-adhered ceramic sheet along edges of an upper die and a lower die to form a sheared film adhered ceramic sheet; wherein: the film-adhered ceramic sheet is sheared by sandwiching and fixing the film-adhered ceramic sheet between the upper die and a second pressing module juxtaposed on the lower die, while simultaneously sandwiching and fixing the film-adhered ceramic sheet between the lower die and a first pressing module juxtaposed on the upper die; the upper and lower dies are then linearly displaced with a predetermined load to shear the film-adhered ceramic sheet; and a clearance is provided and maintained between the edges of the upper and lower dies such that the upper and lower dies do not directly contact a resulting surface of a fracture site.
