Abstract: Provided is a hydrogen gas generating body capable of generating a hydrogen-added liquid in a shorter time than with conventional hydrogen-adding apparatuses. This hydrogen gas generating body is constituted by a hydrogen generating composition that generates hydrogen by retaining water, and a housing body formed to freely house the hydrogen generating composition by having a hydrogen gas permeable film overlaying a backing comprising a pouched non-woven fabric. The invention is also characterized in that: the housing body has the hydrogen gas permeable film overlaid on the inner side of the backing; the housing body has the hydrogen gas permeable film overlaid on the outer side of the backing; or the housing body comprises two layers of the backing with the hydrogen gas permeable film overlaid therebetween.

Abstract: Provided is a hydrogen generation unit which can produce a hydrogen containing liquid more conveniently compared to a conventional hydrogen adding instrument.
