PROBLEM TO BE SOLVED: To provide a laser marking device enhanced in precision for a vertical line or a horizontal line by a laser beam. SOLUTION: This device is provided with a plurality of laser output parts provided respectively with laser sources 11a, for outputting the laser beam, a prism block 21 provided integrally with prism parts 24a, for changing optical paths of the laser beams from the laser sources 11a, to desired directions, and cylindrical lenses for converting the laser beams optical-path-changed by the prism parts 24a, into line light beams, substantially cylindrical laser device main bodies attached adjacently each other to make the laser sources 11a, of the respective laser output parts substantially parallel to an axial direction (vertical direction), and main body support parts for supporting the laser device main bodies with respect to setting-out device main bodies swingably in the whole circumferential direction, and for supporting the laser device main bodies under an erected condition to make the axial direction substantially parallel to a vertical direction by a dead weight of the laser device main bodies.
