Claims

[Scope of utility model registration request]

a light emitting device that irradiates light toward a metal processed surface of a material to be inspected; a light receiving device that receives reflected light from the metal processed surface and detects the presence or absence of a defect on the metal processed surface based on the magnitude of the received light amount; 1. A surface defect detection device for a metal processed surface, comprising a gas blowing means for blowing gas onto the metal processed surface to be irradiated with light to remove deposits adhering to the metal processed surface.
