1. A substrate processing apparatus comprising:

  • a reaction tube configured to accommodate and process substrates;

    a substrate holder configured to hold a plurality of substrates stacked at predetermined intervals in the reaction tube;

    a gas nozzle installed along a stacked direction of the substrates so as to supply a predetermined processing gas to the reaction tube;

    a heating unit configured to heat the substrates;

    a temperature detector installed along the stacked direction of the substrates; and

    an exhaust unit configured to exhaust an inside atmosphere of the reaction tube,wherein each of the gas nozzle and the temperature detector comprises a first part inserted into the reaction tube and parallel with surfaces of the stacked substrates and a second part extending from the first part along an inner wall surface of the reaction tube in the stacked direction of the substrates, andeach of the gas nozzle and the temperature detector is supported by a narrow tube supporting member comprising a first supporting part and a second supporting part,wherein the first supporting part is in contact with the first part, and the second supporting part is parallel with the second part and is configured to support the second part in at least three directions.
