PROBLEM TO BE SOLVED: To provide a gas chromatograph which improves the workability of operations inside an oven, such as column replacement by illuminating the inside of the oven. SOLUTION: A light source 7 for illumination is provided outside the oven, and light is guided to the inside of the oven from the light source 7 by an optical fiber 8. According to this structure, since the inside of the oven can be illuminated, without having to take into consideration the heat resistance of a lighting system, and a hand of a worker is illuminated brightly in replacing the column 4 or conducting a gas leak test, workability is improved.
