Abstract
The hydrogen production device of the present invention includes: a first electrode including a conductive substrate and a photocatalytic semiconductor layer; a second electrode that is electrically connected to the first electrode and disposed in a second region opposite to a first region relative to the first electrode; the first region is defined as a region on a side of a surface of the first electrode in which the photocatalytic semiconductor layer is provided; a water-containing electrolyte solution; and a housing containing these. The first electrode is provided with first through-holes and the second electrode is provided with second through-holes; and the first through-holes and second through-holes form a communicating hole for allowing the first region and the second region to communicate with each other. An ion exchange membrane having substantially the same shape as the communicating hole is disposed in the communicating hole to close the communicating hole.
