There is provided a hydrogen production device which is high in the light use efficiency and can produce hydrogen with high efficiency without decreasing the hydrogen generation rate. The hydrogen production device according to the present invention comprises: a photoelectric conversion part having a light acceptance surface and a back surface; a first gas generation part and a second gas generation part provided on the back surface, wherein one of the first gas generation part and the second gas generation part is a hydrogen generation part to generate H 2 from an electrolytic solution, and the other thereof is an oxygen generation part to generate O 2 from the electrolytic solution, and at least one of the first gas generation part and the second gas generation part is plural, and the photoelectric conversion part is electrically connected to the first gas generation part and the second gas generation part so that an electromotive force generated by a light acceptance of the photoelectric conversion part is supplied to the first gas generation part and the second gas generation part. |
