Abstract
A heat radiation coefficient C [=Ph/(Th−To)] from a microheater is calculated in accordance with a power Ph applied to the microheater which is supported in air and provided in an ambient gas, a heater temperature Th, and an ambient temperature To at this moment. Further, a thermal conductivity λof the ambient gas is obtained from the calculated heat radiation coefficient C based on a proportional relation [C=K·λ] between a thermal conductivity λof the ambient gas and the heat radiation coefficient C at a measurement temperature T [=(Th−To)/2].
