To prevent the breakage of a cutter blade by integrally joining a blade part composed of a TiC material with a base metal composed of a material having the hardness lower than this TiC material.

A plurality of cutter blades 3 are fixed to a surface of a cutter holder 1 for a pellet manufacturing device via a fixed bolt 4 at a prescribed angle. The cutter blade 3 is formed by integrally joining a blade part 3A composed of a TiC material (uniformly dispersed in a stainless matrix containing Ni, Cr, Mo, etc., and composed of a cermet material sintered in vacuum, the cermet material is simply called the TiC material in the following) with a base metal 3B composed of a material (for example, composed of an iron based alloy of stainless steel or carbon quantity of 0.45% or less) having the hardness lower than the blade part 3A.
