PROBLEM TO BE SOLVED: To improve thermal desorption analytical precision by uniformly heating a sample. SOLUTION: This thermal desorption analytical device is equipped with a sample holder for mounting the sample thereon, a sample chamber for arranging the sample holder in the inside, an infrared heating furnace for heating from the periphery, the sample arranged in the sample chamber in the mounted state on the sample holder, a measuring means for detecting gas desorbed from the sample through heating, and an evacuation means for evacuating the sample chamber, a soaking means (a soaking substrate 13 and a soaking hood 14) for soaking the heat by infrared rays, released from the infrared heating furnace via an absorption medium, and heating the sample by secondary radiation, installed near the sample arranged in the sample chamber in a mounted state on the sample holder 10. The soaking means is formed from molybdenum, tantalum, tungsten, or an alloy composed mainly of at least one among them.
