PROBLEM TO BE SOLVED: To provide an epoxy resin powder coating composition developing high adhesiveness, corrosion resistance, flexibility and impact resistance in high reproducibility. SOLUTION: The epoxy resin powder coating composition comprises a bisphenol F solid epoxy resin and a curing agent as essential components. The bisphenol F solid epoxy resin is a solid epoxy resin synthesized from bisphenol F and epichlorohydrin, having epoxy group and phenolic hydroxyl group at the same time, and having an epoxy equivalent of 800-3,000 g/eq and a phenolic hydroxyl equivalent of 1,000-4,000 g/eq.
