The heater 24 inside the electric heating device 20 generates heat under the control performed by the control unit 22. The heat is transferred to the tobacco rod of the non-combustion heating smoking article via the heat transfer member 25, so that the mist generating base material contained in the filler 11 of the tobacco rod is volatilized together with the flavor components.

By the heating of the heater 24, the tobacco rod is heated to approximately 150-250°C.

The heating temperature of the roll paper when measuring the above-mentioned ΔE* is set to 200°C, and the time is set to 5 minutes based on the premise that the electrically heated smoking system of the embodiment of the present invention is used.

The vapor containing the mist generating base material and flavor components generated by heating is vaporized in the inside of the paper tube portion 14 by the mechanism described above, and reaches through the filter portion 15 of the non-combustion heating type smoking article 10 In the user's mouth.

[Example]

The following examples illustrate the present invention in more detail, but the present invention is not limited to the description of the following examples without departing from the spirit.

<Preparation of paper samples>

Cut the commercially available tobacco rod roll paper into 5cm×5cm pieces.

In addition, the heat-sensitive material is selected from the materials shown in Table 1 below, and an aqueous solution of each material is prepared at the concentration shown in Table 1. Using a pen, each aqueous solution was applied to the cut roll paper in a width of 3 cm.

In addition, those who did not coat the cut roll paper described above were used as a control group. In commercially available roll paper for tobacco rods, the content of citric acid (which is described as a coating amount in Table 1, but is not coated) as a combustion enhancer is about 1.2% by weight relative to the total volume of the roll paper.

Furthermore, a commercially available self-extinguishing tobacco rod roll paper (with a self-extinguishing agent coated on the surface in contact with tobacco shreds) was prepared as Comparative Example 1.

Each sample was placed on household aluminum foil paper (material: aluminum foil thickness: 11 μm), and heated at 200° C. for 5 minutes in a reheating furnace (product name: Muffle Furnace F0410 model, manufactured by Yamato Scientific).

<Color difference measurement>

Using a spectrophotometer (manufactured by X-Rite, product name SpectroEye), ΔE* was measured for each sample before and after heating. The measurement was performed under the conditions of light source D65, no light source filter, and viewing angle of 2°. One piece of sample was placed on a paper with an ISO whiteness of 92%, and the spectrophotometer was pressed against the upper side.

The measurement is performed on the part coated with the heat-sensitive material in 5 repeated measurements, and the average value is used for analysis.

The results of the color difference measurement are shown in Table 1.

From the results in Table 1 above, it can be seen that the color difference ΔE* before and after heating at 200°C for 5 minutes when an aqueous solution containing the substances shown in Table 1 is applied as a heat-sensitive material to the roll paper is 15 or more, On the other hand, the color difference ΔE* in the control group or Comparative Example 1 was less than 15%. In addition, regarding the sample with a color difference ΔE* of 15 or more, although the color change was such that the color difference ΔE* before and after heating became 15 or more, under the observation of the sensory inspector, the uncomfortable color was not recognized even after heating. .

On the other hand, with regard to the control group or Comparative Example 1 in which the color difference ΔE* was less than 15, the appearance after heating was slightly uncomfortable under the observation of the panelists compared with the appearance before heating.
