Beschreibung
Zusammenfassung:	A cutting apparatus for a ceramic green sheet according to the present invention is a cutting apparatus for a ceramic green sheet for cutting a ceramic green sheet held on a carrier film into a square-shaped sheet piece, and comprises four roller cutters, each of which is disposed so as to correspond to each edge of the sheet piece, and moving means for moving the roller cutters along the corresponding edges of the sheet piece. In this cutting apparatus, the four edges of the sheet piece are cut by the roller cutters, thus cutting failures on the ceramic green sheet are significantly prevented. Furthermore, each of the edges of the sheet piece is cut without changing the position of the cutters, thus improvement of cutting dimensional accuracy is realized, compared to the conventional apparatus in which the position of the cutter is changed when cutting each edge.
