Abstract
Provided is a gas concentration measuring device including a heat generating resistor that generates heat when electricity is supplied and a stage supporting the resistor. The resistor and the stage overlap in plan view. The stage has a plan view area S of 3.6×10μmor less. The ratio of the area S to the total volume V of the heat generating resistor and the stage, S/V, ranges from 0.0010 to 10 μm. The device is configured to measure an oxygen gas concentration in a sample gas on the basis of the resistance of the heat generating resistor.
