PROBLEM TO BE SOLVED : To provide an element to be served for a hydrogen gas sensor having high sensitivity and quick responsiveness by using a stably-suppliable inexpensive material without using a rare metal such as palladium, and to provide a miniaturized hydrogen gas sensor by providing a sensor element having high sensitivity.SOLUTION : In this element for the hydrogen gas sensor, a plurality of carbon nanotubes 22 are disposed between a board-like first collector electrode 10 and a board-like second collector electrode 30 arranged approximately in parallel separately at a prescribed distance, and the plurality of carbon nanotubes 22 are separated mutually so that hydrogen gas 40 can pass between adjacent carbon nanotubes 22, erected approximately vertically to a first collector electrode surface 10a and a second collector electrode surface 10b respectively, and connected electrically to the first collector electrode 10 and the second collector electrode 30.COPYRIGHT : (C)2012, JPO&INPIT |
