Abstract
A magnesium alloy sheet is made of a magnesium alloy containing Al. Particles of an intermetallic compound containing at least one of Al and Mg are present in the sheet in a dispersed state. The sheet includes an oxide film which extends substantially over the surface of the sheet and which has a uniform thickness. The average size of the particles of the intermetallic compound is 0.5 μm or less. The percentage of the total area of the particles is 11% or less. Therefore, the magnesium alloy sheet is excellent corrosion resistance. A magnesium alloy structural member is provided.
