PROBLEM TO BE SOLVED: To provide a gas detection device that reduces dilution of desorbed component gas during a time period until the desorbed component gas is guided to a gas detection unit since the component gas condensed in an adsorbent member id desorbed, and has detection accuracy improved.SOLUTION: A gas detection device according to the present invention comprises: a housing that has a ventilation unit extending in a vertical direction inside the housing; ventilation means for ventilating gas to the ventilation unit; an adsorbent member that adsorbs component gas included in the gas; a heating unit that heats the adsorbent member; and a gas detection unit that detects the component gas. The adsorbent member and gas detection unit are disposed inside the ventilation unit, in which the gas detection unit is disposed in a vertical upper part of the adsorbent member. |
