PROBLEM TO BE SOLVED: To provide a thermosetting powder coating material for a wheel, a method for forming a coating film by using the coating material, a manufacturing method for a painted product therewith, and the painted product. SOLUTION: The thermosetting powder coating material for the wheel contains (A) a carboxy group-containing thermosetting polyester resin, (B) an epoxy resin, (C) a hydroxy group-containing polymer, and (D) a phosphoric acid-modified epoxy resin obtained by reacting a phosphate compound (a) with an epoxy compound (b). The phosphate compound (a) has at least one P-OH bond obtained by reacting a monoglycidyl ether compound and/or a monoglycidyl ester compound with phosphoric acid, and the epoxy compound (b) has at least one epoxy group.
