Abstract
The present invention couples a housing including a gas separation membrane to a sensor unit capable of detecting the concentration of hydrogen gas such that liquid cannot permeate a closed space within the housing and only hydrogen gas dissolved in the liquid can permeate the closed space through the gas separation membrane, and detachably couples such a hydrogen sensor element to an opening of a container in which the liquid is held. Accordingly, the present invention can measure the concentration of dissolved hydrogen gas in a simple manner.
