Zusammenfassung:	To provide a laser processing apparatus and a laser processing method capable of performing heat-treatment that meets a wide variety of needs for round bar-shaped workpieces having various shapes and dimensions.SOLUTION: A laser processing apparatus 1 of the present invention that heat-treats a round bar-shaped workpiece 5 includes: a galvano scanner 2 for scanning and condensing a laser beam 4; a tubular reflector 3 for reflecting the laser beam 4 emitted from the galvano scanner 2 and irradiating it to the workpiece 5, in which the reflector 3 has a shape that is rotationally symmetric with respect to a central axis passing through radial centers of two ends 30, 31 of an axial direction, and has an inclined surface 32 inclined from one of the two ends 30, 31 toward the other.SELECTED DRAWING: Figure 1 【課題】様々な形状及び寸法の丸棒状のワークに対する多種多様なニーズの熱処理が可能なレーザ加工装置及びレーザ加工方法を提供する。【解決手段】本発明のレーザ加工装置１は、丸棒状のワーク５に熱処理をするためのレーザ加工装置１であって、レーザ光４を走査して集光するためのガルバノスキャナ２と、ガルバノスキャナ２から出射されたレーザ光４を反射してワーク５に照射する筒状の反射鏡３と、を備え、反射鏡３は、軸方向の２つの端部３０，３１の径方向の中心を通る中心軸に対して回転対称の形状であって、２つの端部３０，３１の一方から他方に向けて傾斜した傾斜面３２を有することを特徴とする。【選択図】図１
