The hollow tube heater has a compression cylinder part that compresses the tobacco rod part from the outer circumferential side when the tobacco stick is inserted, and a heating wall part that is formed by at least a part of the compression cylinder part and that heats the tobacco rod part from the outer circumferential side. The tobacco filling is wrapped with rolling paper with the cut tobacco in a randomly oriented state. The cross-sectional area of the tobacco rod part is defined so as to be greater than the cross-sectional area of the inner space of the compression cylinder part and so that the tobacco rod part is compressed by the inner wall of the compression cylinder part when inserted into the compression cylinder part.
