PROBLEM TO BE SOLVED: To provide a hydrogen storage device shortened in the filling time of hydrogen as a storage device and excellent in high efficiency discharge property as a hydrogen electrode by particularly mixing a flake like hydrogen occlusion alloy with a flake like metallic powder, regarding the hydrogen storage device and its producing method, and the hydrogen occlusion alloy electrode and its producing method. SOLUTION: The hydrogen storage device which absorbs and discharges hydrogen is formed by uniformly mixing the flake like hydrogen occlusion alloy powder with the flake like other metallic powder. Other metallic powder is composed of a metal having higher thermal conductivity than that of the hydrogen occlusion alloy. As the surface condition of the powder of hydrogen occlusion alloy and the other metal, both surface evenness rate is <=4 and the ratio of the average diameter of other metallic powder to that of hydrogen occlusion alloy powder is <=0.6. |
