A heat processing apparatus comprises a heating furnace, a process tube located in the heating furnace and having an open bottom, a manifold connected to the open bottom of the process tube, a sealing member sandwiched between the process tube and the manifold to air-tightly seal the process tube, a fixing member for fixing the process tube to the manifold, a heat transmitting member made of metal and sandwiched between the fixing member and the process tube to radiate heat at that area of the process tube, which is opposed to the fixing member, to the fixing member by heat conduction, and a heat exchange conduit arranged in the fixing member and having a passage through which heat exchanging medium flows to cool the fixing member by heat exchange.
