PROBLEM TO BE SOLVED: To provide a laser processing device and a laser processing method with which removal efficiency of molten material by laser beam irradiation is improved, and with which the molten material is properly collected.SOLUTION: A laser processing device 1 includes at least: a laser head 3a for irradiating a processing object site of a workpiece 2 with a laser beam 3 to melt a laser beam irradiation section 2a; and a liquid supply nozzle 4a for injecting liquid to a position separated by a prescribed distance from the laser beam irradiation section 2a to form a fluid liquid film 6 on a surface of the workpiece 2. A melting section material 2c of the laser beam irradiation section 2a is removed by the liquid 4 injected from the liquid supply nozzle 4a.SELECTED DRAWING: Figure 1 【課題】レーザー光照射による溶融物の排除効率を向上し得ると共に、当該溶融物を適切に回収し得るレーザー加工装置及びレーザー加工方法を提供する。【解決手段】レーザー加工装置１は、少なくとも、レーザー光３を被加工物２の加工対象箇所に照射しレーザー光照射部２ａを溶融するレーザーヘッド３ａ、及びレーザー光照射部２ａと所定の距離離間する位置に液体を噴射し流動性の液膜６を被加工物２の表面に形成する液体供給ノズル４ａを備え、レーザー光照射部２ａの溶融部物２ｃを液体供給ノズル４ａから噴射される液体４により除去する。【選択図】 図１
