PROBLEM TO BE SOLVED: To provide a laser distribution device capable of safely and surely switching the transmission destination of the laser of high output without loss. SOLUTION: This laser distribution device 20 is provided with a pentagonal prism 30 attached to a supporting body 34 to be moved along a guide rail 32 and plural laser emission ports 26. When a screw shaft 38 screwed to the supporting body 34 is rotated by a step motor 40, the pentagonal prism 30 is moved to a position facing a desired laser emission port 26. In this case, when the laser is made incident on the pentagonal prism 30, the laser is reflected by changing a direction by 90 degrees and led to the desired laser emission port 26.
