Abstract
A degradable structural member made of a magnesium alloy has a sufficient strength and is degradable at a proper timing in an aqueous environment. The magnesium alloy contains not less than 7.0% by mass and not more than 13.0% by mass of Al, not less than 4.5% by mass and not more than 13.0% by mass of Cu, and greater than 0% by mass and less than 0.10% by mass of Mn, with the balance being Mg and unavoidable impurities. The Al, Cu, and Mg are formed as finely dispersed intermetallic compounds throughout the magnesium alloy.
