PROBLEM TO BE SOLVED: To provide a drying device capable of easily controlling the quantity of wind of an inner chamber structure nearly constant and easily changing the drying capacity according to the drying condition of an object for drying. SOLUTION: An upper wind passage 5A, a left wind passage 5B and a right wind passage 5C are formed between an inner wall part of a nearly box-shaped dryer body 2 and an outer wall part of the inner chamber structure 3, and a plurality of air holes 3A communicating with the left wind passage 5B or the right wind passage 5C are bored on the left and right sides of the inner chamber structure 3 to form an air circulation route R. The part of the upper wind passage 5A opposite to the ceiling part of the inner chamber structure 3 is divided into upper and lower two spaces: an upper air duct 7 and a lower air duct 8. A fan 10 for dehumidification is attached inside the upper air duct 7 and also a cooler 11 is attached on the downstream side of the fan 10. In addition, a fan 12 for adjustment is attached inside the lower air duct 8.
