The invention provides a cutter for forming cutting holes which can eliminate the problems of reduced free degree in design, difficulty in reducing resistance and the like, and a binding machine comprising the cutter. The cutter is used in the binding machine (1), the binding machine (1) forms through holes (P1) and cutting holes (P2) on a plurality of sheets of paper (P), front ends (P51) of cutting-turning pieces (P5) which are cut from the through holes (P1) and are turned up partially inserted through the cutting holes (P2), and the plurality of sheets of paper (P) can be mutually bound by snapping the cutting-turning pieces (P5) with the cutting holes (P2). The cutter can form the cutting holes (P2) and is characterized by having a window (331) for holding the cutting-turning pieces (P5) to be inserted through the cutting holes (P2), and an edge (332) of the window (331) which is used for pressing the cutting-turning pieces (P5) so that the cutting-turning pieces are dragged into the cutting holes (P2) is in a shape of an area (335) distributed in the thickness direction and has a thickness size larger than raw materials of the cutter. |
