| Zusammenfassung: | An object of the present invention is to provide a gas sensor device capable of detecting a temporal change with high accuracy and maintaining measurement accuracy over a long period under a temperature environment susceptible to a complicated and wide range of change.The gas sensor device includes: heat insulating films 8a and 8b formed on a substrate 2; a first heater 3 provided on the heat insulating films 8a and 8b and configured to measure physical quantity of gas; and a reference resistor 4 formed in a resistive layer same as the first heater and formed on the heat insulating films 8a and 8b. The gas sensor device further includes a second heater 5 that simultaneously heats the first heater 3 and the reference resistor 4. |
