FIG. 1 shows a smoking article according to a reference example . This smoking article is treated in a conventional manner into a cylinder formed of a wrapping paper 2 having a porosity of 4 to 150, preferably 20 to 80, in units of Coresta. A tobacco rod 1 is provided which is filled with smoking material such as tobacco leaves cut and chopped at a packing density of 150 to 300 mg / cm 3 . The hot gas passage 3 extends in the longitudinal direction of the tobacco rod, and the peripheral wall 4 of the passage is substantially impermeable to paper.
Alternatively, it is manufactured from a reconstituted tobacco sheet . When one end of the smoking article is lit, the smoke flows along the tobacco rod 1,
On the other hand, the air flows to the filter unit 5 along the hot gas passage 3. The hot gas passes through the particulate aggregate 6 and desorbs and releases predetermined components from the particulate 7. The desorbed components form an aerosol and reach the smoker's mouth through a second filter at the mouth end. As this second filter the components desorbed from the particulate matter is supplied to the mouth of the most smokers, it is preferable that the ability to capture desorbed component is very small, like a normal cigarette filter, cellulose acetate, Made of polypropylene, paper or other similar filter material.

In addition , this smoking article is of a type in which the filter unit 5 retains heat. That is, the smoking article includes an insulating region 12 formed of, for example, ceramic fibers or other insulating fibers. This insulation zone serves to prevent excessive dissipation of heat to the surroundings and at the same time to prevent the temperature rise outside the smoking article. If necessary, the heat insulating region 12 can also function as a filtering means, and in this case, a material other than fine fibers can be used.

One of the objects of the present invention arises from tobacco leaves,
The amount of pyrolysis or combustion products provided to the smoker may be substantially reduced and the smoker may be provided with a simulated tobacco smoke aerosol. To achieve this, certain components and / or perfumes are impregnated and adsorbed on the granules of the filter unit. When a cigarette is ignited, the air sucked into the tubular passage provided in the tobacco rod is heated by the burning of the smoking material, and this hot gas activates the particulate matter and adsorbs the components. And / or release and release perfume. The vapor thus generated condenses to form an aerosol and is supplied to the suction side. Since the peripheral wall of the tubular passage is non-breathable, no hot gas diffuses to the tobacco rod or tobacco smoke diffuses into the passage.
