Abstract

Provided are a gas sensor, a gas detection device, a gas detection method and a device provided with the gas detection device, capable of improving gas detection performance. The gas detection device is provided with a gas sensor comprising a thermosensitive resistance element and a porous gas molecule adsorptive material thermally bonded to the thermosensitive resistance element that releases specified gas molecules due to heating and cooling, and a power supply control unit that heats and cools the thermosensitive resistance element by controlling the supply of power thereto. The gas detection method comprises a heating step for putting the porous gas molecule adsorptive material in a heated state and a detecting step for detecting a specific gas due to the temperature change in the thermosensitive resistance element by heating.
