The present invention is to provide a component for machine structure with a hardened layer formed by high-frequency hardening. The hardened layer has a hardness of not less than Hv 750 and an average prior austenite grain size of not greater than 7 mm across the entire thickness. This component for machine structure is greatly improved in fatigue strength when compared with conventional components for machine structure.
