PROBLEM TO BE SOLVED: To provide an energy saving type distortion removing heating furnace for a small lamp which can uniformly and surely remove the distortion generated by the heating and transformation process. SOLUTION: The distortion removing heating furnace for small lamp comprises a tunnel type heating furnace body 2 constructed so as to gradually reduce the temperature inside the furnace toward one end, a conveying system 3 arranged along the heating furnace body 2, holding and conveying processed small lamps 5 in the heating furnace body 2 toward one end, a temperature reflection body 6, separately arranged at outer circumference of the heating furnace body 2, forming an air layer (an aerial area) between the outer peripheral surface of the heating furnace body 2 and itself, and a body of equipment 8 arranged at outer periphery of the temperature reflector 6, forming a vacuum layer 9 at the outer periphery of the temperature reflector 6.
