PROBLEM TO BE SOLVED: To provide a leaf tobacco dryer of energy-saving type that levels and equalizes the temperature and humidity in a drying chamber, stabilize drying operation control, improves the qualities of dried leaves and reduces the fuel consumption. SOLUTION: The leaf tobacco dryer of energy-saving type has a constitution such that a waste heat recovery part 14 for recovering an exhaust heat from the exhaust outlet 13 of the leaf tobacco drying chamber 3 and heating open air (In), which is sucked from an air inlet 11, is installed in a hot air generator 2; a far-infrared radiation plate 24 for receiving a radiant heat from a furnace 6 and radiating a far-infrared radiation is arranged between the furnace and the lower part of the leaf tobacco drying chamber 3; and during a leaf tobacco drying operation, dried mixed air that is mixed air of the heated open air (In) and ventilation air and reheated by the furnace 6, and a far-infrared radiation radiated from the heat-accumulated far-infrared radiating plate 24 are supplied simultaneously to the leaf tobacco drying chamber 3.
