Abstract: In order to provide a more practical gas analysis device than that having conventionally been, while keeping the laser source and the photodetector separated from the gas cell, thereby preventing exposure to a high temperature, the gas analysis device includes: a gas cell; a laser source or a photodetector separated from the gas cell; and a laser light transmission mechanism provided between the gas cell and the laser source or the photodetector. The laser light transmission mechanism includes one or a plurality of tubular members, and an inner space of the one or the plurality of tubular members provides a light path for the laser light.
