PROBLEM TO BE SOLVED: To provide a thermosetting multilayer coating film which has an excellent appearance property equivalent to a case of using a solvent clear paint as a top coat, and physical properties and chemical properties which bear comparison with the case at a practical level, can be suitably used for exterior coating especially of vehicles such as automobiles or vehicle components, does not require conventional technologies, such as "atomization" and "spheronization" of powder clear paint, aiming at improving the appearance property, and does not require drastic change of manufacturing processes. SOLUTION: In the powder clear paint that forms a final coating film on a primer aqueous base coat paint, a flow index value measured by a dynamic viscoelasticity measuring device under a specific condition is controlled within a desired range.
