Abstract: A cutter blade according to an embodiment includes: an insert member including a cutting-edge part configured to slide along a plate surface of a die plate, the plate surface having holes formed therein, and thereby to cut a material extruded 5 from the holes onto the plate surface, and an insert part having a first surface and a second surface opposed to the first surface, the insert part being connected to the cutting-edge part; and a main part configured to support the insert member by sandwiching the first and second surfaces.

Abstract: A cutter blade and a method for manufacturing a cutter blade capable of reducing the manufacturing cost are provided. A cutter blade according to an embodiment includes a blade edge part configured to slide along a plate surface of a die plate, the plate surface having holes formed therein, and thereby to cut a plurality of pieces of a material extruded from the holes onto the plate surface, and a base metal part to which the blade edge part is bonded by an adhesive. The blade edge part may be bonded to the base metal part in such a manner that the blade edge part can be replaced with a new one.
