Abrégé

Provided is a metal member imparted with a compressive residual stress that is effective for improving resistance to permanent strain. The surface portion of the metal member is rapidly heated. One example of the metal member is a spring member. A load is applied to the heated metal member so as to impose a larger plastic strain to the surface portion of the metal member than to the inside thereof. By removing the load, compressive residual stress is generated in an area from the surface of the metal member to a position at a first depth (D1) or deeper than the first depth (D1). The compressive residual stress increases in the direction from the inner side of the metal member toward the surface thereof and is substantially maximized at the surface. The compressive residual stress increases at a higher rate at portions close to the surface than on the inner side.
