PROBLEM TO BE SOLVED: To provide a hydrogen storage material which is rather lightweight and has high hydrogen storage ability at normal temperature and low hydrogen pressure and a fast absorption and emission rate of hydrogen. SOLUTION: The hydrogen storage material 1 contains a plurality of carbon carriers 2 consisting of a carbon material having electric conductivity and a plurality of fine particles 3 having hydrogen adsorptivity carried by the carbon carrier 2. The proportion A of the fine particles 3 carried is in the range of 0.1 wt.%<=A<=20 wt.%. The fine particles 3 are at least one kind selected from single metal fine particles, alloy fine particles and oxide semiconductor fine particles. As for the alloy, for example, an alloy composed of at least one kind selected from Mg, Ti, rare earth elements, Zr, V, Ca and Al and at least one kind selected from Fe, Co, Ni, Cu, Mn, Mo and W is used. |
