PROBLEM TO BE SOLVED: To provide a chemical polishing liquid with which, in a metallic material having a sharp corner part on the surface, the corner part can be preferentially etched/polished, and rounded, to provide a chemical polishing method, and to provide a metallic material produced by being subjected to chemical polishing. SOLUTION: The chemical polishing liquid comprises: an oxidizing agent of etching a metallic material; a film forming agent of forming a corrosion resistant film on the surface of the metal so as to prevent its oxidation caused by the oxidizing agent; and a dissolving agent. The film forming agent is hard to stick to the sharp corner part, and, even if it sticks thereto, the film is formed only thinly compared with a flat part. Thus, the oxidizing agent in the mixed liquid does not substantially etch the flat part, but preferentially etches/polishes the corner part, and can round the same. COPYRIGHT: (C)2006,JPO&NCIPI
