PROBLEM TO BE SOLVED: To provide a highly practical hydrogen occlusion material a constitution element of which is Li. SOLUTION: This hydrogen occlusion material has the following compositional formula: Li<SB>1-x-y</SB>Si<SB>x</SB>M<SB>y</SB>(wherein M is at least one selected from Be, B, C, N, Na, Mg, Al, P, K, Ca, Ga, Ge, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ag, Pd, Y, Zr, Nb and rare earth elements; 0<x<1; and 0≤y<1). Since Li and Si are fundamental constitution elements, the hydrogen occlusion material is light in weight and inexpensive. The hydrogen occlusion, a discharge temperature (operation temperature) and the amounts of hydrogen occlusion and discharge are easily controlled by adjusting the adding ratio of Si, the kind of the added element M and its adding ratio.
