This specification discloses an optical processing head including a light guide portion that guides, to a process surface, a ray for processing. The light guide portion is further configured to guide, to the process surface, a ray for inspection different in wavelength from the ray for processing. The optical processing head further includes an inspection portion that inspects the state of the process surface based on reflected light of the ray for inspection reflected by the process surface. With the optical processing head, the state of the process surface can be easily inspected even during optical processing.
