Abstract
The present invention has a hydrogen detection portion composed of a semiconductor and a hydrogen absorber provided at least a part of a surface thereof, and pairs of electrodes provided at the semiconductor so as to sandwich the place at which the hydrogen absorber is provided and so as not to be electrically connected to each other with the hydrogen absorber, wherein the presence of hydrogen can be detected by the change in resistance of the semiconductor in response to hydrogen absorption into the hydrogen absorber, the change in resistance being measured between said pairs of electrodes.
