Provided is a hydrogen generator wherein the entire surface of a photocatalyst, which has a complicated structure, can be irradiated with light. This hydrogen generator comprises water (40), a photocatalyst (20) and a light source (30) that emits light for causing a photocatalytic action of the photocatalyst; and this hydrogen generator generates hydrogen by decomposing water by means of the photocatalyst (20) that is irradiated with light. A liquid light source is used as the light source (30). Consequently, the photocatalyst (20) can be irradiated with light from the liquid light source (30), while bringing the liquid light source (30) closer to or into contact with the photocatalyst (20). As a result, the entire surface of the photocatalyst, which has a complicated shape, can be irradiated with light. |
