PROBLEM TO BE SOLVED: To provide a gas thermal conduction type gas sensor capable of sufficiently correcting an error due to a change of an environmental temperature even when the environmental temperature largely fluctuates.SOLUTION: A gas thermal conduction type gas sensor 100 includes: a sensor section 10 including a detection element part 40 in which a resistance value changes on the basis of thermal conduction with an atmospheric gas, and a temperature correction element part 50 which is connected to the detection element part 40 in series and which configures a bridge circuit together with the detection element part 40; a constant current supply section 20 for supplying a constant current to the sensor section 10; and a correction section 30 for correcting output from the sensor section 10 under an environmental temperature on the basis of a voltage of the sensor section 10 under a reference temperature and a voltage of the sensor section 10 under the environmental temperature in such a state that the constant current is supplied by the constant current supply section 20.SELECTED DRAWING: Figure 1
