<P>PROBLEM TO BE SOLVED: To provide a gas sensing device for detecting a specific component in expiration, converting the detection result to sensory irritation, and reporting it. Ž<P>SOLUTION: The gas sensing device 10 includes a plurality of sensors 48 and 50 for detecting and outputting mutually different components, and a control circuit 32 and loudspeaker 38 that are connected to the sensors and report the measurement result by auditory sensory irritation in response to the combination of output levels of the sensors. Each of the sensors 48 and 50 includes a CNT structure surface-modified with a material selected correspondingly to the component to be detected, and a detection circuit for outputting a concentration signal of the specific component in response to variation in electric resistance of the CNT structure.
