PROBLEM TO BE SOLVED: To provide a hydrogen generator with which the product lifetime of a reaction vessel can be made longer.SOLUTION: In a hydrogen generator, a metal having an oxide film and a reaction agent are stored in a reaction vessel of which the inside is in an oxygen-free state, and hydrogen is generated by heating the reaction vessel with a heating means, wherein the reaction vessel is formed so as to be hollow and includes a weld where the end of the reaction vessel is welded with a blocking member, and the weld is arranged apart from the heating means along a longitudinal direction for the purpose of preventing heating of the weld. |
