The present invention is a laser processing device wherein adhesion of fumes to a lens can be effectively avoided. The laser processing device is provided with a laser scanner provided with protective glass on a laser output opening, and a cylindrical member having a through path through which the laser output via the protective glass passes formed on the center side in the direction of the radius. A cylindrically shaped filter is disposed on an inside wall part of the cylindrical member facing the through path. The cylindrical member discharges a gas into the through path from the filter.

Laser processing device with tubular filter

This laser irradiation mechanism includes a control unit which has a function allowing the focal point of a laser beam to describe a circle, performs control such that the focal point describes a spiral, and performs control such that the central axis of the spiral moves along a curved surface.
