Abstract
A sensor is constituted by joining a pair of electrodes to a sensor body formed by binding hydrogen occluding metal with binders. Change in the electric resistance between the electrodes and the quantity of hydrogen occluded by the hydrogen occluding metal in the sensor body has a one to one relationship. Therefore, the quantity of hydrogen occluded by the hydrogen occluding metal can be estimated from the resistance value obtained by the sensor.
