Zusammenfassung:	To provide a manufacturing method of a motor coil, which forms an oxide film with sufficient insulation property.SOLUTION: A manufacturing method of a motor coil forms an oxide film on a surface of a copper plate 1 on which the coil is formed by laser. The motor coil includes: a shield gas supply part 30 for supplying shield gas 31; and an oxidation gas supply part 20 which supplies either ozone gas, halogen gas or oxygen. The oxidation gas supply part supplies oxidation gas 21 after a weld part 2 is formed on a surface of the copper plate.SELECTED DRAWING: Figure 1 【課題】十分な絶縁性を有する酸化膜を形成するモータ用コイルの製造方法を提供すること。【解決手段】本開示に係るモータ用コイルの製造方法は、レーザによってコイルを形成する銅板１の表面に酸化膜を形成するモータ用コイルの製造方法であり、シールドガス３１を供給するシールドガス供給部３０と、オゾンガス、ハロゲンガス、酸素のいずれかを供給する酸化ガス供給部２０と、を備え、酸化ガス供給部は、銅板の表面に溶接部２が形成された後に酸化ガス２１を供給するものである。【選択図】図１
