To provide a heating device capable of increasing the kinds of applicable heating object article materials.SOLUTION: A heating device comprises: a blower for taking outside air into a device provided with a furnace body 20 in an enclosure; an upstream side heater 61 heating gas flowing through the inside of the device by the blower; a downstream side heater provided at the more downstream side in a direction where the gas flows than the upstream side heater 61 and heating the gas; a fan 70 stirring the gas heated by the downstream side heater and thereafter made to flow into the furnace body 20; a branch flow passage 23 provided so as to branch from a flow passage for exhausting the gas from the inside of the furnace body 20 to the outside of the device and feeding a part of the gas exhausted from the inside of the furnace body 20 from the upstream side heater 61 into the flow passage reaching the downstream side heater; and a damper 80 switching the opening and the braking of the branch flow passage 23.SELECTED DRAWING: Figure 2 【課題】適用可能な加熱対象品の材料の種類を多くすることのできる加熱装置を提供する。【解決手段】筐体内に炉本体２０を備える装置内に外気を取り込むためのブロワと、前記ブロワによって装置内を流れる気体を加熱する上流側ヒーター６１と、上流側ヒーター６１よりも気体が流れる方向の下流側に配され、かつ気体を加熱する下流側ヒーターと、前記下流側ヒーターによって加熱された後に、炉本体２０の内部に流入した気体を撹拌するファン７０と、炉本体２０の内部から装置外に気体を排気するための流路から分岐するように設けられて、上流側ヒーター６１から前記下流側ヒーターに至る流路中に炉本体２０の内部から排出された気体の一部を送り込む分岐流路２３と、分岐流路２３の開放と遮断を切り替えるダンパー８０と、を備えることを特徴とする。【選択図】図２
