PROBLEM TO BE SOLVED: To provide a thermal decomposition treatment method whereby a hot air gas flows to the same direction as the carriage direction of an article to be treated and the load of energy is reduced and thereby a thermal decomposition treatment device and facility can be surely miniaturized. SOLUTION: The flowing direction of the hot air gas to a first thermal decomposition is the same as the direction to which the article to be treated is carried. The flowing direction of the hot air gas to a second thermal decomposition device 10 is also the same as the direction to which the article to be treated is carried. The hot air gas is supplied to the first thermal decomposition device 1 at a part wherein the heat capacity is the most required, and the hot air gas is supplied to the second thermal decomposition device 10 at a part wherein the heat capacity is not required so much. Therefore, the hot air gas is introduced into a heating jacket 3 of the first thermal decomposition device 1 at a part on a charging side of the article to be treated, and the hot air gas is introduced into a heating jacket 13 of the second thermal decomposition device 10 at a part on a communicating duct 15 side from a hot air furnace 20.
