PROBLEM TO BE SOLVED: To provide a lightweight hydrogen storage material which has a low hydrogen absorbing/discharging temperature and a high absorbing/discharging rate, thus can store a large quantity of hydrogen, and is particularly useful for a fuel battery by adding metal powder having hydrogen molecule dissociation catalytic capacity and a flocculation preventive agent to magnesium simple substance or magnesium-based alloy powder, and ball-milling them. SOLUTION: The hydrogen storage material comprises magnesium or magnesium-based alloy powder as the main components, comprises metal powder having hydrogen molecule dissociation catalytic capacity such as nickel, titanium, palladium, vanadium and platinum, and further comprises metal chloride such as sodium chloride, potassium chloride, nickel chloride, magnesium chloride and iron chloride or metal hydride such as lithium hydride, calcium hydride and magnesium hydride present as solid at an ordinary temperature by 10 to 40 wt.%.
