Abstract: The present invention relates to a flammable gas detection sensor that is a gas detection sensor which converts heat generated by the catalytic reaction between the catalyst component and a flammable gas to a voltage signal by a thermoelectric conversion effect and detects this signal as a detection signal, and is characterized by comprising as constituent elements thereof a catalyst component for initiating a catalytic reaction when in contact with a gas to be detected, and a film of thermoelectric conversion material which converts local temperature differences brought about by heat generated by the reaction to voltage signal; and also relates to a flammable gas concentration measurement method and a measurement apparatus thereof.
