A Mg alloy member with an anticorrosive coating free from any enviromental load can be produced by using a solution for chemical conversion treatment for anti-corrosive coating, which comprises 0.05 to 1 mol/l of an oxoacid compound of heavy metal selected from Mo, W and V and has a pH of 2 to 6 adjusted by sulfuric acid or nitric acid, and is characterized by contacting the surface of Mg alloy preferably containing 2 to 10% Al with the solution, thereby forming a specific oxide film and, if necessary further forming a fluorine-containing organic film on the film, the resulting Mg alloy member being used in electrically driven blowers (601), note-type personal computers, various household electrical appliances, etc. |
