PROBLEM TO BE SOLVED: To provide a hydrogen inhalation device and a capsule which allow hydrogen inhalation to be performed divided into several times of inhalation, by performing only once preparation operation.SOLUTION: The hydrogen inhalation device comprises: a steam generating part for generating steam; a storage part for storing metal hydride; an introduction part for introducing the steam generated by the steam generating part into the storage part; and a suction port for inhalation of hydrogen generated by chemical reaction between the steam and the metal hydrate. When the suction port is sucked, the steam is introduced into the storage part to generate hydrogen.SELECTED DRAWING: Figure 1【課題】準備作業を一度行えば、水素吸入を数回に分けて行うことが可能な水素吸入装置及びカプセルを提供すること。【解決手段】水素吸入装置は、蒸気を生成する蒸気生成部と、水素化金属を格納する格納部と、蒸気生成部で生成した蒸気を格納部に導入する導入部と、蒸気と前記水素化金属との化学反応により発生した水素を吸入するための吸口とを備え、吸口が吸引された場合に、蒸気が格納部に導入され水素が発生する。【選択図】図1
