PROBLEM TO BE SOLVED: To provide a method for manufacturing a heat-curing powder water dispersion coating composition. SOLUTION: The method is characterized by combining a heat-curing base resin having a base resin such as an acrylic resin, a polyester resin, a fluororesin, a silicone resin, an epoxy resin, a amine-modified resin, a phenol resin, a urethane resin and the like introduced with a functional group such as a hydroxy group, a carboxy group, an epoxy group and an unsaturated group thereto with a curing agent having a functional group which is curable with these functional group, for example, such as a blocked ployisocyanate compound, a polyepoxide, a polycarboxylic acid compound, an acid anhydride, a carboxy group- and acid anhydride group-containing carboxylic acid compound, an amino resin, a phenol resin, a hydrazide compound, a peroxide and the like, melt-kneading the resultant to obtain a heatcuring powder resin composition and wet-dispersing the heat curing powder resin composition with a volume average particle diameter of 10-100μm using a pipeline bead mill, thereby obtaining the heat-curing powder water dispersion coating composition having a volume average particle diameter of 5-20μm.
