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).
A gas sensor, comprising:
A gas detection method for a gas sensor comprising a heat sensitive resistive element having at least a pair of electrodes, a lead part which is electrically connected to the heat sensitive resistive element by welding, while having no inclusions, and a porous gas molecule adsorption material which is thermally coupled to the heat sensitive resistive element, has a pore, and adsorbs molecules with a diameter smaller than a diameter of the pore, wherein adsorbed specific gas molecules are desorbed by heating to change a temperature due to desorption, the method comprising:
