To provide a cut structure by which force required in cutting a plurality of sheets simultaneously along perforations can be reduced and the sheets can be cut accurately along the perforations.

A sheet-like object has perforations for cut on each sheet, and is formed of a plurality of sheets by stacking sheets so as to be cut simultaneously along the perforations for cut. The perforations for cut are formed by shifting positions of a cut part or a hinge part on each sheet. Thereby, a perforation structure can reduce force required to cut a sheet piece along the perforations, and enables the sheet piece to be accurately cut along the perforations as compared with the case of overlapping and simultaneously cutting the plurality of sheets having a same perforation structure.
