In such a method, a coated article(coated gears, or the like), wherein the coating film 5 having the uniform thickness on uneven parts is formed, can be obtained. In the electrostatic powder coating, for example, a powder coating material based on a thermoplastic resin such as a nylon based resin can be used. A thickness of the coated film may be about 150-200 μm. A ratio of a coating weight (g/m
2 ) of the primary powder layer to the coating weight (g/m
