A method of manufacturing a semiconductor device includes the steps of: conveying a plurality of substrates disposed in a direction perpendicular to a substrate processing surface into a processing chamber provided inside of a reaction tube, with an outer periphery surrounded by a heating device; and processing the substrates by introducing gas to a gas inlet tube provided on a side face of the reaction tube in a region for processing the substrates inside the reaction tube, so as to reach at least an outside of the heating device, and spouting the gas into the processing chamber from a slit-shaped gas spouting port disposed in a form so as to straddle at least a plurality of the substrates in a direction perpendicular to the substrate processing surface. |
