Abstract
A catalysis combustion type gas sensor that detects an inflammable gas includes a heat-insulating portion; a heater that is formed on the heat-insulating portion; a gas reaction film that is formed on the heater on the heat-insulating portion and includes a carrier carrying a combustion catalyst for the inflammable gas; a temperature-measuring element that is formed in the vicinity of the gas reaction film on the heat-insulating portion; and a soaking portion that is formed on the heat-insulating portion and is arranged between the heat-insulating portion and the gas reaction film. The soaking portion is configured so as to decentralize heat transferred to the soaking portion in the entire soaking portion.
