Abstract: Provided is an exhalation sensor that utilizes heat effectively and can operate with low power consumption. The exhalation sensor has a surface layer on its surface that faces a sensor main body, and the performance of the surface layer to reflect radiant heat is higher than that of a housing. Specifically the radiant heat reflectivity of the surface layer is higher than that of the housing. Therefore, the surface layer can reflect radiant heat emitted from the sensor main body more efficiently than the housing. The radiant heat emitted from the sensor main body is less likely to escape to the outside of the housing, so that the heat generated by a heater of the sensor main body can be efficiently stored within the housing. This can reduce the power consumed by the heater to heat a conversion section and a sensing section to their operating temperatures.
