To make a generation speed of hydrogen faster by making a catalytic activity and a reaction surface area of a catalyst body coming into contact with a hydrogen generating agent larger when the hydrogen is generated by making the hydrogen generating agent contact with the catalyst body.
The catalyst body in which a surface of a metal substrate itself is constituted as Raney type catalyst is obtained by alloying the metal substrate becoming a catalyst with an eluting metal, covering with it and then eluting the eluting metal. Alternatively, the catalyst body in which the surface of the metal substrate is integrated and covered with Raney type catalyst metal is obtained. The generation speed of hydrogen is increased, for example, by applying these catalyst bodies to a hydrogen generation device. Further, there is no fear that the catalyst metal is peeled off and generation of hydrogen is stabilized for a long period of time.
