PROBLEM TO BE SOLVED: To provide a laser marker capable of maintaining high precision against to the environment and the laps of years as well as capable of easily and highly precisely adjusting the plurality of line lights. SOLUTION: The laser marker is provided with the lens barrel 5, the laser beam source 7 provided in the lens barrel 5, the beam splitter, the deflection lens for adjusting the light path split from the beam splitter of the laser beam, and the lens holder for holding the conversion lens for converting the laser beam into the line light. Therein, the cylindrical storage hole (first bore part) 6 having an identical shape with the outline of the laser light source 7 is provided at the proper part of the lens barrel 5, and the laser light source 7 is fit to the storage hole 6, at a part of the storage hole 6 of the lens barrel 5 a groove 8 larger than the storage hole 6 is formed. To the groove 8, the clamp 10 having a second bore part 9 of an identical shape with the laser light source 7 is provided in the external radial direction of the laser light source 7 swingably, and the laser light source 7 is fixed by pressing the clamp 10 from the counter radial direction of the laser light source 7.
