PROBLEM TO BE SOLVED: To provide a trivalent chromium plating bath capable of being used for the plating of industrial products with chromium, which is excellent in usability. SOLUTION: The trivalent chromium plating bath contains a trivalent chromium salt (chromium chloride), a first organic compound-based complexing agent (potassium formate), a second organic compound-based complexing agent (lactic acid), a buffer agent (boric acid), an electroconductive salt (potassium chloride), a corrosion inhibitor (potassium bromide), a surface controlling agent (polyethylene glycol 400) and a hardener (strontium chloride).
