Zusammenfassung:	To provide a metal-coated magnesium wire suitably available as a hydrogen storage material and a production method thereof.SOLUTION: A metal-coated magnesium wire 1 comprises: a core material 2; and a metallic outer covering layer 3 with which an outer peripheral surface of the core material 2 is covered. The outer covering layer 3 has a hydrogen permeable performance under atmospheric pressure. The core material 2 is composed of an assembly of a plurality of coated filaments 4. Each of the coated filaments 4 is formed by coating a filament body 41 composed of magnesium or a magnesium alloy with a coating layer 42. The coating layer 42 has a hydrogen permeable and oxygen non-permeable performance under the atmospheric pressure. The coating layer 42 is composed of such a metallic material as causes no interdiffusion between the metallic material and the filament body 41.SELECTED DRAWING: Figure 1 【課題】水素吸蔵材料として好適に利用可能な金属被覆マグネシウム線及びその製造方法を提供する。【解決手段】金属被覆マグネシウム線１であって、芯材２と、芯材２の外周面を被覆する金属製の外装層３とを含む。外装層３は、大気圧下において水素を透過する性能を有する。芯材２は、複数の被覆フィラメント４の集合体からなる。被覆フィラメント４のそれぞれは、マグネシウム又はマグネシウム合金からなるフィラメント本体４１が被覆層４２で被覆されたものである。被覆層４２は、大気圧下において水素を透過するが酸素を透過しない性能を有する。被覆層４２は、フィラメント本体４１との間で相互拡散しない金属材料からなる。【選択図】図１
