An object of the present invention is to provide a hydrogen gas suction tool which can be carried by a user freely and which can further adjust the concentration to supply hydrogen gas. A hydrogen gas suction tool for generating and sucking hydrogen gas, which is a first hydrogen gas suction tool main body hollow at least inside, a suction side hollow layer internally connected by a low pressure check valve, and A second hydrogen gas suction tool main body having an intake side hollow layer, and a variable pressure control valve capable of adjusting and passing a hydrogen gas concentration between the first and second hydrogen gas suction tool main bodies； A substance capable of generating and reacting hydrogen and water for reaction can be placed on the intake side hollow layer inside the second hydrogen gas suction tool main body by contacting with water. [Selected figure] Figure 1【課題】本発明は、ユーザが携帯して自由に持ち運べ、さらに濃度を調整して水素ガスを供給可能な水素ガス吸引具を提供する。【解決手段】水素ガスを発生させて吸引するための水素ガス吸引具であって、少なくとも内部が中空な第１水素ガス吸引具本体と、内部に低圧逆止弁で繋がった吸引側中空層及び吸気側中空層を有した第２水素ガス吸引具本体と、前記第１及び第２水素ガス吸引具本体の間に水素ガス濃度を調整して通過させることが可能な可変式圧力制御弁と、が備えられ、前記第２水素ガス吸引具本体内部の吸気側中空層には、水と接触することで水素発生反応する物質と反応用水を載置可能であることを特徴とする。【選択図】 図１
