Abstract: A gas measurement device is provided to maximize a light traveling distance in a minimum space by using a plurality of reflecting mirrors so as to improve the sensitivity of a sensor for a small variation in the quantity of gas. A gas measurement device(100) includes a light source emitting light, a detector(40) detecting the light emitted from the light source, a filter(41) included in the detector to pass only a wavelength region of gas, which is to be measured, and a guide(60) for guiding the light emitted from the light source to the detector to increase the traveling distance of the light. The guide includes a plurality of bent guide channels(20) and a plurality of reflecting mirrors(30) placed at bent portions of the guide channels.
