A hydrogen gas generating member includes a metal alloy having dispersed aluminum. The metal alloy includes an Al-X alloy, where X is Sn: 10.1 to 99.5% by mass, Bi: 30.1 to 99.5% by mass, In: 10.1 to 99.5% by mass, Sn +Bi: 20.1 to 99.5% by mass, Sn +In: to 10 to 99.5% by mass, Bi+In: 20.1 to 99.5% by mass, or Sn+Bi+In: 20 to 99.5% by mass. Hydrogen gas is generated by bringing the hydrogen gas generating member into contact with water.
