To provide a manufacturing method of a coated article, which comprises asking a physical quantities by a fluid simulation without coating using an actual coating machine or a test model close to the actual coating machine, and setting coating conditions based on the physical quantities.
The manufacturing method of the coated article comprises the step of setting coating conditions using the coefficient A(t) shown in a formula (1) asked from the simulation results by a numeric fluid analytic method to coat. In the formula, So represents a coated substrate exit cross section, and Gi(t) represents an area ratio in which a gas part occupies in a micro area dS in a time t. The dS is a micro area factor constituting the coating substrate exit cross section.
