  • a wrapping paper 1 (basis weight: 124.7 gsm, thickness: 157 ⁇ m) was obtained by stacking the cut three layers and pressurizing the stacked layers while applying heat (laminating) to the stacked layers. As a result that the paper layer is compressed during lamination and part of the paper layer is embedded in the thermoplastic resin layer (here, laminate layer), the obtained wrapping paper is thinner than the total thickness of the thicknesses of the layers before lamination.
  • the ground tobacco material 1 and tobacco material 2, the pH adjustor, and the binder were prepared as raw materials and mixed, kneaded with addition of water, and the obtained kneaded product was granulated by a wet extrusion granulator (made by Dalton Corporation; mesh size ⁇ 0.9mm, temperature of a kneaded product at the extrusion outlet 50 to 60°C).
  • the contents of the components in the raw materials were 50.00 wt% of tobacco material 1, 12.50 wt% of tobacco material 2, 25.00 wt% of water, 7.50 wt% of flavor developing agent, and 5.00 wt% of binder.
  • the kneaded product was dried with a drier until 12.50 wt% of water, and then classified by a grinding classifier (made by Freund-Turbo Corporation; mesh size upstream ⁇ 710 mm, downstream ⁇ 250 mm).
  • the average particle size of the obtained granules was 530 ⁇ m.
  • the flavor material was added with a pipet such that the content of the flavor material in the tobacco granules was 9.09 wt%, and rotationally agitated for 24 hours or longer in a vial container under an environment of 22°C to be uniformly dispersed.
  • the pH of the obtained tobacco granules was 9.5 (measurement temperature 22°C).
  • the contents of the components in the obtained tobacco granules were 53.03 wt% of tobacco material 1, 13.26 wt% of tobacco material 2, 11.36 wt% of water, 7.95 wt% of pH adjustor, 5.30 wt% of binder, and 9.09 wt% of flavor material.
  • the tobacco granules were disposed between two filters, and these were wrapped with the wrapping paper 1 to obtain the cylindrical non-combustion-heating-type tobacco (cartridge).
  • Vinyl acetate was used as a binder at the time of bonding the first paper layer and the third paper layer of the wrapping paper into a cylindrical shape.
  • the diameter of the bottom was 7.8 mm
  • the height in the long-axis direction was 20 mm
  • the volume ratio (packing fraction) of tobacco material in the space section was adjusted as shown in Table 1 by changing the filling amount of the tobacco material.
  • the volume specific gravity of each tobacco material is shown in Table 1.
  • the air-flow resistance of each non-combustion-heating-type tobacco in the long-axis direction was as shown in Table 1.
  • the measurement was performed by disposing one of the filters as a bottom. Then, tobacco material was moved such that the tobacco material was substantially uniformly dispersed on the inner surface of the filter serving as the bottom.
  • each non-combustion-heating-type tobacco was manufactured by changing the type and filling amount of tobacco material.
  • the average particle size of tobacco granules of Lot2 was 630 ⁇ m
  • the average particle size of tobacco granules of Lot3 was 250 ⁇ m.
  • the above-described cartridge was inserted in the flavor inhalation system (electrically heated tobacco product) shown in Fig. 3 , a tobacco rod inhalation port end was inserted in a five-link-type rotary automatic smoker made by Borgwaldt. Then, after a lapse of 30 seconds from the time point (heating start time point) at which the heater switch was turned on, smoking was started. Measurement was performed under the conditions of Health Canada smoking method (smoking with a smoking amount of 55 cc/2 sec, a smoking time of 2 sec, a smoking interval of 30 sec, and the number of times of smoking of 13). Main-stream smoke components were trapped by preinstalled glass fiber filters (trapping Cambridge filters (produced by Borgwaldt, 400 Filter 44 mm)).
