Disclosed is a high toughness magnesium-base alloy containing, on a weight basis, 1-8% of a rare earth element and 1-6% of calcium, wherein the maximum crystal grain size of magnesium which constitutes the base metal is not more than 30 μm. An intermetallic compound (6) of at least one of the rare earth element and calcium has a maximum particle size of not more than 20 μm, and dispersed in crystal grain boundaries (5) and crystal grains (4) of the magnesium base metal.
