Abstract
A gas sensor comprises first and second light emitting parts, first and second light receiving parts, and first and second optical path regions, wherein the optical path regions have a common region, a first light receiving part has a larger rate of change of an output signal with respect to a first gas than a second light receiving part, the second light receiving part has a larger rate of change of an output signal with respect to an second gas than the first light receiving part, the first light receiving part has a sensitivity peak wavelength closer to a first wavelength in an absorption wavelength band of the first gas than the second light receiving part, and the second light receiving part has a sensitivity peak wavelength closer to a second wavelength in an absorption wavelength band of the second gas than the first light receiving part.
