• the tobacco sheets can be produced by combining tobacco raw materials with an aerosol former, a binder, and the like, and then using the above-mentioned process.
• the tobacco sheets produced in this manner can be shredded to a predetermined size, and wrapped in cigarette paper with the resulting tobacco shreds facing inward to form a cylindrical tobacco rod (Patent Document 1).
• the tobacco sheet can be gathered and then formed into a cylindrical tobacco rod without being shredded (Patent Documents 2 to 4).
• Patent Document 5 a tobacco material in which sheets of different sizes are packed in layers is also known.

• the esterified raw material is a petroleum-derived raw material made by chemical synthesis from petroleum, and the use of such petroleum-derived raw materials can cause an increase in the burden on the environment.
• acetate filters and other filters are components that can increase the burden on the environment through the use of the above-mentioned raw materials and substances, and from the perspective of reducing the burden on the environment, it is desirable to reduce the amount of such filters used, and it is even more desirable not to use such filters at all.
• non-combustion heat smoking article that does not include a filter segment, but does include a tobacco-containing segment, offers a variety of advantages, including reduced environmental impact, elimination of the need for a process for assembling filter segments into tobacco-containing segments, and the ability to make packaging more compact.
