<P>PROBLEM TO BE SOLVED: To produce a carburized component having excellent impact strength and bending strength which have not been obtained heretofore by performing carburizing and quenching, also refining crystal grains and removing a carburized abnormal layer on the surface. Ž<P>SOLUTION: A steel for a machine structure is formed into a component shape by machining or forging, is thereafter subjected to gas carburizing and quenching, is thereafter subjected to induction hardening for one or more times, and is subsequently tempered, and, after that, the surface of the carburized component subjected to the tempering is removed by 5 to 100 μm, so as to remove a carburized abnormal layer, and thus the carburized component having excellent impact strength and bending strength is manufactured.
