摘要： A method of manufacturing a metal part in which a base material of an aluminum alloy as an anode is immersed in an electrolyte together with a cathode, and at least a portion of a surface of the base material is anodized and coated with an anodic oxide film, the method includes: increasing a current density provided to both the anode and the cathode from an initial current density of 0 A/dm2 at a rate that is lower than or equal to 0.35 A/dm2 per minute, wherein once the current density reaches a prescribed current density, the current density provided to the anode and the cathode is maintained at the prescribed current density.
