A hydrogen generating device comprises a first plate having plural first grooves, plural first walls which define the first grooves, an alumina layer formed by anodic oxidation at least in part of the surface of the first walls, and a first catalyst layer containing heteropolyacid to be carried on the alumina layer, and a second plate arranged oppositely to the first plate, the second plate having plural second grooves formed to correspond to the first grooves one by one, plural second walls which define the second grooves, and a second catalyst layer formed at least in part of the surface of the second walls. The first walls are inserted into the second grooves, and the second walls are inserted into the first grooves, whereby the first and second walls are located opposite to each other and apart from each other by not larger than 500 mum, respectively.
