Abstract
A manufacturing method for a shaftby imparting a residual compressive stress to an inner surfaceof the lateral holeof the workpieceincludes a disposing step and an irradiation step. In the disposing step, a lateral-hole mirroris disposed inside the lateral hole. In the irradiation step, a laser beam L is emitted from one of an inner-side openingand an outer-side openingof the lateral holetoward the lateral-hole mirror, making the laser beam L reflect on the lateral-hole mirror, and thereby applying the laser beam L to the inner surfaceof the lateral hole
