To provide a hydrogen generation method for easily generating hydrogen and to provide a hydrogen generating and storing apparatus which can easily generate and store hydrogen and repeatedly store and release hydrogen.

Aminoborane (NH3BH3) is decomposed to generate hydrogen by using a mechanical means. The hydrogen generating and storing apparatus 1 is equipped with a container 2 and aminoborane 4 housed in the container 2. The aminoborane 4 is decomposed by using a mechanical means to generate hydrogen in the container 2.
