Provided is a thermosetting powder coating obtained by the following procedure: preparing a suspension by dispersing a resin solution containing an organic solvent into an aqueous solution containing a water-soluble polymer; removing the organic solvent in a dispersed phase from the suspension; solidifying particles in the dispersed phase; and removing the solidified particles in the dispersed phase from the suspension. The thermosetting powder coating is characterized in that the resin solution contains: acrylic resin containing epoxy groups and blocked isocyanate groups; and, as a curing agent, a carboxylic group- or carboxylic anhydride group-containing compound.
