To provide a metal foamed body having fine foam which exhibits high strength and further has a high foam fraction, and to provide a method for producing a metal foamed body in which fine foam is uniformly dispersed.
The metal foamed body is composed of silicon-containing aluminum alloy, and has the average foam size of 2 mm. The metal foamed body is produced through: a preparation stage where a powdery mixture of alloy powder composed of a silicon-containing aluminum alloy and foaming auxiliary powder decomposed by heating so as to generate a gas is prepared; a compacting stage where the powdery mixture is compacted so as to obtain a compact; and a heating-foaming stage where the compact is heated at the solidus temperature of the aluminum alloy or above and also less than the liquidus temperature so as to foam the foaming auxiliary powder.
