In a laser hardening device for the inner surface of a cylinder, which hardens the inner surface of a cylinder by scanning the laser beam in the circumferential direction, the reflecting surface of the reflecting mirror is oriented in a direction in which the ridge line is perpendicular to the incident optical axis and the reflected optical axis of the laser beam. A laser hardening device for the inner surface of a cylinder, characterized in that the laser beam reflected by the reflecting surface is diffused in the longitudinal direction of the cylinder by forming a convex curved surface.
