Abstract
(EN)
Provided are: a gas sensor which is able to have improved gas detection performance, while being capable of suppressing variation in the output characteristics among individual gas sensors; a gas detection device; a gas detection method; and a device which is provided with a gas sensor or a gas detection device. This gas detection device (10) is provided with: a heat sensitive resistive element (2); a lead part (22b) which is connected to the heat sensitive resistive element (2) by welding, while having no material being interposed therebetween; a gas sensor (1) which is thermally coupled to the heat sensitive resistive element (2), while comprising a porous gas molecule adsorption material (3) from which specific gas molecules are desorbed by means of heating; and an electric power supply unit which supplies electric power to the heat sensitive resistive element (2), thereby heating the heat sensitive resistive element (2).
