To prevent the corrosion by a dry distilled gas, of a furnace main body and to reduce radiation loss.
In this induction heating type pyrolysis furnace, a dry distillation tank for putting a dry-distilled substance is mounted in a furnace main body 1 of refractory creating an inert gas atmosphere, and the dry distillation tank is induction-heated by a heating coil 3 mounted outside of the furnace main body to perform dry distillation treatment of the dry distilled substance, a heat insulating material 9 is mounted on a wall face of the furnace main body. Whereby the radiation loss from the furnace wall is reduced by mounting the heat insulating material, and a thickness of the refractory can be thinned by that much, which reduces a weight of the furnace and increases the heating efficiency by the heating coil. By mounting the heat insulating material inside of the furnace main body, the refractory composing the furnace main body can be protected from the corrosion by a dry distilled gas.
