A laser marking apparatus is provided with a laser emission unit (13) that emits laser beam and a laser radiation unit (14) that is detachably connected to the laser emission unit (13). The laser radiation unit (14) radiates the laser beam emitted from the laser emission unit (13) toward an object to be processed. A projection (44), which projects rearward, is formed on a part of the laser radiation unit (14) that is connected with the laser emission unit (13). A recess (28) is provided in a part of the laser emission unit (13) that is connected with the laser radiation unit (14). The projection (44) can fit into the recess (28). The recess (28) is opened forward, backward, to lateral sides, and downward. |
