PROBLEM TO BE SOLVED: To provide a laser head for laser markers that facilitates work for matching a laser light, for example, in a vertical direction to a laser point on a laser light, for example, in a horizontal direction in the laser head showing the laser point on the laser line, and can reduce the costs of the laser marker having the laser head and miniaturizing the laser marker. SOLUTION: In the laser head 40, two rod lenses 20 are arranged with a narrow space 44, and a light axis 36 in laser beams passing through a lens unit 18 from a semiconductor laser 14 is allowed to pass through the space 44, thus facilitating work for matching the position of the laser point 32a in a horizontal direction to that of the laser line 28b in a vertical direction, when equipping the laser marker 10 with the laser head 40 in a horizontal direction and the laser head 40 in a vertical direction.
