Abstract: The present invention relates to a gas sensor employing a non-dispersive infrared (NDIR) scheme. The gas sensor may comprise: a light source portion for emitting light; a light cavity portion for multi-reflecting the emitted light; a light detecting portion for detecting the multi-reflected light; a first light coupling portion for reflecting and concentrating the light emitted by the light source portion toward the light cavity portion; and a second light coupling portion for reflecting and concentrating the light reflected by the light cavity portion toward the light detecting portion. The first light coupling portion may comprise a light emitting surface that faces a side surface of the light cavity portion and has a via hole through which light passes, and a reflecting surface extending from the light emitting surface so as to surround the upper portion and the side portion of the light source portion such that light emitted by the light source portion is reflected toward the via hole of the light emitting surface. The second light coupling portion may comprise a light incident surface that faces a side surface of the light cavity portion and has a via hole through which light incident from the light cavity portion passes, and a reflecting surface extending from the light incident surface so as to surround the upper portion and the side portion of the light detecting portion such that light incident from the light cavity portion is reflected toward the light detecting portion.
