Corrosion resistance and provides excellent magnesium alloy member. The magnesium alloy member has a layer formed by a method as described comprising a magnesium alloy containing Al more than 7.5% by mass, the chemical conversion to the surface of the substrate. In a substrate, precipitates, typically include an intermetallic compound containing at least one of Al and Mg, and having an average particle diameter of dispersed particles of not more than than 0.05 ㎛ 1 ㎛. The total surface area of the particles, is 1 area% to 20 area% or less. System layer, in order from the base side and a lower layer, the surface layer, the surface layer, it is denser than the lower layer. The magnesium alloy member, as much amount of Al of the substrate, by having a dense layer on the surface of, Formula layer with high corrosion resistance of the substrate itself, it is difficult for the etchant to penetrate the substrate, is excellent in corrosion resistance. Difficult by providing the porous lower layer, layer system with the impact being separated from the base material, it is easy to maintain a high corrosion resistance.
