PROBLEM TO BE SOLVED: To provide an adjusting method of a marking laser device capable of performing highly accurately angle adjustment of an optical system without enlarging the marking laser device. SOLUTION: The marking laser device includes a cylindrical lens for widening beam light into linear light, and a curved surface having a prescribed curvature is formed on a member on which the cylindrical lens is mounted, and the cylindrical lens is provided slidably along the curved surface. Since adjustment is performed by sliding the cylindrical lens along the curved surface of the optical system, angle adjustment of the optical system can be performed highly accurately without enlarging the marking laser device.
