<1-1. Winding part>
[First Region and Second Region of Winding Part]
As shown in FIG. 1, the winding portion formed by winding the tobacco rod portion 10 and the mouthpiece portion 11 with the tipping paper 12 is composed of a first region 12a and a second region 12b. Although not shown in FIG. 1, the tobacco rod portion 10 is formed by wrapping a tobacco filler with wrapping paper, as will be described later. Furthermore, the tipping paper is coated with a lip release agent 13 at least partially.
The first region 12a is a region in the longitudinal direction of the non-combustion-heating tobacco and includes the mouth end portion of the non-combustion-heating tobacco, and the second region 12b is located closer to the first region than the first region. This is a region located on the tobacco rod side of the winding portion. The first area and the second area are adjacent areas.
In FIG. 1, the lip release agent in the first region is the portion indicated by 13a, and the lip release agent in the second region is the portion indicated by 13b.
The content of the lip release agent per unit area in the first region is also simply referred to as "the amount of lip release agent in the first region", and the content of the lip release agent per unit area in the second region is , also simply referred to as "the amount of lip release agent in the second region".

In conventional non-combustion heated cigarettes, the entire surface of the tipping paper is usually coated with a lip release agent, and the concentration of the lip release agent is varied within the surface, that is, to satisfy the above condition (A). It is not done to apply a lip release agent to. In this case, although the lip release property, which is the purpose of coating the lip release agent, can be achieved, a substance derived from the lip release agent generated by heating is generated from the entire surface of the tipping paper during use.
On the other hand, when the lip release agent is applied so as to satisfy the above condition (A), the lip release agent in the first region not only ensures the lip release property, but also the lip release in the second region. Since the amount of agent is less than the amount of lip release agent in the first region, the amount of substances derived from the lip release agent during use is reduced compared to the conventional non-combustion heated cigarettes described above. At least a portion of the tipping paper is coated with a lip release agent, but from the viewpoint of ensuring lip release properties, the portion coated with the lip release agent is the filter portion that can be provided in the mouthpiece portion, which will be described later. It is preferable that at least a part of the region of the tipping paper existing directly under the tipping paper is coated, and it is also a preferable embodiment that the entire surface of the region is coated.
Modes of the first region and the second region are not particularly limited, but particularly preferred modes will be described below.

(1) First aspect In the first aspect of the first region and the second region, the first region extends from the mouth end of the non-combustion-heating tobacco in the longitudinal direction of the non-combustion-heating tobacco. It is an area up to a position of 17 mm, and the second area is an area from the position of 17 mm to the tobacco rod side end in the longitudinal direction of the wound portion.
In general usage of non-combustion heating tobacco, if a lip release agent is applied to the first region, which is a region from the mouth end of the non-combustion heating tobacco to a position of 17 mm, during use Considering the contact area (also referred to as "lip contact area") between the smoker's lips and the non-combustion heating cigarette, sufficient lip release properties can be ensured. Furthermore, by reducing the coating amount of the lip release agent in the second region, which is the region from the 17 mm position to the tobacco rod side end in the longitudinal direction of the wound portion, the lip release agent-derived The amount of substances generated can be reduced.

The position from the mouthpiece side end of the non-combustion heating cigarette that separates the first region and the second region can be set to 17 mm for the reason described above. From the viewpoint of being able to reduce the amount, it is preferably 15 mm, more preferably 13 mm, and particularly preferably 10 mm. If the position is brought closer to the mouthpiece end side than this, it becomes difficult to secure the lip release property.

(2) Second Aspect A second aspect of the first region and the second region is that the first region has the above-described The second region is the region from the 42.5% position to the tobacco rod side end in the longitudinal direction of the wrapping part. This is an embodiment characterized in that it is a region of
As in the first aspect above, considering the general mode of use of non-combustion-heated tobacco, the length of the wrapping portion in the longitudinal direction of the non-combustion-heated tobacco is: If the lip release agent is applied to the first region, which is the region 42.5% from the mouthpiece side end of the cigarette, sufficient lip release property can be secured, and during use, It is possible to reduce the amount of substances generated from the lip release agent in.

The ratio from the mouth end of the non-combustion-heating tobacco to the length of the winding portion in the longitudinal direction of the non-combustion-heating tobacco, which divides the first region and the second region, is for the above reasons. Although it can be 42.5%, it is preferably 37.5%, more preferably 32.5%, from the viewpoint of being able to reduce the amount of substances derived from the lip release agent during use. More preferably, 25% is particularly preferred. If the position is brought closer to the mouthpiece end side than this, it becomes difficult to secure the lip release property.

(3) Third Aspect The mouthpiece portion of the non-combustion heating tobacco of the present embodiment may have a cooling portion and a filter portion. A third aspect of the first region and the second region, which is an aspect that can be taken in this case, is that the cooling portion has a plurality of openings, and the plurality of openings are formed on the outer peripheral surface of the cooling portion. Circumferentially arranged, the first region extends from the mouth end of the non-combustion-heating tobacco to the arrangement position of the opening with respect to the length of the winding portion in the longitudinal direction of the non-combustion-heating tobacco. and the second region is a region from the arrangement position of the opening to the tobacco rod side end in the longitudinal direction of the wound portion.
The openings in the cooling part make it possible to control the flow of air and smoke in the cooling part and the filter part by introducing dilution air from the openings to the suction end side during use. . Generally, the area on the mouth end side of the position where the opening is provided becomes the lip contact area. In other words, if the lip release agent is applied to the region on the mouth end side of the opening position, sufficient lip release performance can be ensured. As described in the first aspect, by reducing the coating amount of the lip release agent in the second region, it is possible to reduce the amount of substances derived from the lip release agent during use. In particular, usually, the flow of air and smoke in the mouthpiece portion changes with the opening position as a boundary, and the temperature of the wound portion on the mouth end side of the opening changes to the temperature of the wound portion on the tobacco rod side of the opening. , the amount of substances derived from the lip release agent is greatly reduced by reducing the content of the lip release agent in the winding part on the tobacco rod side rather than the opening position. can be made
The apertures described above are sometimes referred to in the art as "ventilation apertures."

The openings are arranged in the circumferential direction of the outer peripheral surface of the cooling portion (specifically, arranged on the surface perpendicular to the longitudinal direction of the non-combustion heating tobacco in the cooling portion), but the openings are arranged in the circumferential direction. The number of arrangements (also referred to as "circumferential arrangement") is not particularly limited, and may be two or more. In this case, the circumferential arrangement is generally provided in the lip contact area. Since it is outside, the circumferential arrangement that is the boundary between the first area and the second area is the circumferential arrangement closest to the mouthpiece end.
The position of the opening is not particularly limited, but from the viewpoint of reducing the amount of substances derived from the lip release agent during use, the length of the wound portion in the longitudinal direction of the non-combustion heating tobacco On the contrary, it is preferably 17 mm, more preferably 15 mm, even more preferably 13 mm, and particularly preferably 10 mm from the mouth end of the non-combustion heating tobacco.

It is possible to use a sheet, a polymer-based sheet, a metal foil such as an aluminum foil, or the like. Note that the tipping paper as used herein is a sheet that connects a plurality of segments in a non-combustion heating tobacco, such as connecting a tobacco rod portion and a mouthpiece portion, for example.

The method for producing the chipping paper is not particularly limited, and a general method can be applied. In the papermaking process using a short composite paper machine or the like, there is a method of adjusting the texture and making it uniform. If necessary, a wet strength agent may be added to impart water resistance to the wrapping paper, or a sizing agent may be added to adjust the printing quality of the wrapping paper.

<1-2. Lip release agent>
The solid content of the lip release agent in the present embodiment may be 100% nitrocellulose or 100% ethyl cellulose in consideration of the ease of analysis and the actual solid content. Moreover, the mixture which mixed these with arbitrary ratios may be sufficient. Moreover, the solid content of the lip release agent may be a mixture further containing components other than nitrocellulose and/or ethylcellulose.
Conventionally, in non-combustion heating cigarettes, no investigation has been conducted on the effects of lip release agents on smoking taste and the like. The present inventor prepared a non-combustion heating tobacco having a wrapping portion coated with a lip release agent on the entire surface, and a non-combustion heating tobacco that satisfies the above condition (A). An experiment was conducted to compare the content of TSNA contained in tobacco between the two. As a result, it was found that the non-combustion heating tobacco having a wrapping portion coated with a lip release agent on the entire surface contains more TSNA than the non-combustion heating tobacco that satisfies the condition (A). I found out. The inventor considered the cause of this as follows.
Nitrocellulose, which is a nitrate ester of cellulose, is a typical component used in lip release agents. Nitrocellulose is usually obtained by treating cellulose with a mixed acid of nitric acid and sulfuric acid. The nitrocellulose was decomposed by heating to produce nitric acid, and the nitric acid reacted with minor alkanoids in the tobacco raw material to produce TSNA. A non-combustion heating tobacco having a wrapping portion coated with a lip release agent on the entire surface contains a lip release agent more than a non-combustion heating tobacco having a wrapping portion partially coated with a lip release agent. Larger area to be heated. Therefore, it is considered that the heat of the heater is directly or indirectly transmitted to the lip release agent and part of the lip release agent is excessively heated, resulting in the above results.
TSNA is a generic term for tobacco-specific nitrosamines, N'-nitrosonornicotine (NNN), 4-(N-nitrosomethylamino)-1-(3-pyridyl)-1-butanone (NNK) , N′-nitrosoanatabine (NAT), N′-nitrosoanabasine (NAB).

When nitrocellulose is contained in the lip release agent, TSNA is generated as described above. contained in the drug. For example, ethyl cellulose, which can be used as a lip release agent, may cause undesired changes in smoking taste and the like.
The material contained in the lip release agent in the present embodiment is not particularly limited, and examples thereof include nitrocellulose, ethyl cellulose, and mixtures thereof. Nitrocellulose is included from the viewpoint of being able to suppress the generation of TSNA. It is particularly advantageous for lip release agents.

The lip release agent may contain components other than the above nitrocellulose and ethyl cellulose, and for example, fillers such as calcium carbonate can be used. Commercially available products can be used as the components of these lip release agents.

A method for applying the lip release agent to the tip paper is not particularly limited, and a general application method can be applied. The lip release agent can be used as an aqueous solution or ethyl acetate solution of usually 1.0 to 30.0% by weight. can be applied to the tipping paper according to the embodiment of the present invention. The lip release agent may be applied to the tipping paper according to the embodiment of the present invention by known means other than printing, such as a method of applying opaque ink by inkjet printing, a method of spraying, or a method of impregnation.
In addition, the lip release agent must be applied to at least part of the outer surface of the first region of the tipping paper, and may be applied to the inner surface as well. However, from the viewpoint of reducing the amount of substances derived from the lip release agent during use, it is preferable that the inner surface of the tipping paper is not coated with the lip release agent.

[Content of lip release agent]
The content of the lip release agent satisfies the condition (A) as described above.
By satisfying the condition (A), it is possible to ensure the lip release property, reduce the generation of substances derived from the lip release agent during use, and reduce the generation of substances that adversely affect smoking taste. can be suppressed.
The ratio of the content of the lip release agent per unit area in the second region to the content of the lip release agent per unit area in the first region is not particularly limited. From the viewpoint of reducing the amount of substances derived from the lip release agent, it is preferably 1/2 or less, more preferably 1/4 or less, particularly preferably 1/6 or less, and 1/8 or less. is most preferred.

The content of the lip release agent per unit area in the first region is not particularly limited as long as it is higher than the content of the lip release agent per unit area in the ^second region. It is 1.00 μg/mm ² or less, preferably 0.25 μg/mm ² or more and 0.75 μg/mm ² or less.

The content of the lip release agent per unit area in the second region is not particularly limited, but from the viewpoint of reducing the amount of lip release agent-derived substances generated during use, the amount of lip release agent-derived substances generated during use ^From the ^viewpoint of ^{reducing the} It is most preferred that it is, that is, uncoated.
The method for measuring the content of the lip release agent is not particularly limited. After dividing them, weigh them, subtract the weight of the tipping paper in each area to calculate the coating weight of the lip release agent, and divide them by their respective areas to obtain the first area and It is possible to obtain the content of the lip release agent per unit area in the second region.
Also, if it can be calculated, the value obtained by dividing the coating weight of the lip release agent at the time of manufacture by the area, or the coating weight obtained from the weight difference of the tip paper before and after the lip release agent is applied to the target area You may adopt the value divided by the area of .
In addition, since the lip release agent has the property of turning brown when heated to a certain degree, as a simple method for estimating the degree of content of the lip release agent, the tip paper surface before and after the use of non-burning tobacco A method of observing the degree of discoloration can be employed.

Also, the content of the lip release agent can be measured by spectrophotometry. For example, when nitrocellulose is used as the lip release agent, the value calculated by the following method can be used.
First, a standard sample for a calibration curve is prepared by the method shown below, absorbance is measured, and a calibration curve is created from the results of the absorbance measurement of the standard sample for a calibration curve according to ASTM D3133-01. Then, a measurement sample is prepared by the method shown below, and absorbance measurement is performed. The weight of nitrocellulose contained in the measurement sample can be obtained from the calibration curve and the results of the absorbance measurement of the measurement sample, and by dividing this by the area of the target region, the coating of the lip release agent on the target region. You can ask for the quantity.
If the component of the lip release agent is other than nitrocellulose, the same measurement can be performed by changing the acetone described below to a solvent in which the component can be dissolved or by changing the absorption wavelength.

<Preparation of standard sample for calibration curve>
(1) About 6 g of a standard sample (rip release agent before coating) is weighed into a container such as an eggplant-shaped flask, and then concentrated by removing volatile components using an evaporator.
(2) While dissolving the obtained non-volatile components in acetone, transfer to a 100 ml volumetric flask with a pipette and make up to 100 ml with acetone.
(3) Four 50-ml eggplant-shaped flasks were prepared, and 0, 1, 3, and 5 ml of the solution obtained in (2) were weighed into each, and 10, 9, and 7 were added so that the total volume was 10 ml. , 5 ml of acetone are added.

Alternatively, dried tobacco leaves may be pulverized and homogenized to have an average particle size of 20 to 200 μm and processed into a sheet (hereinafter also simply referred to as a homogenized sheet), which may be chopped. Further, it may be a so-called strand type in which a homogenizing sheet having a length approximately equal to the longitudinal direction of the tobacco rod is chopped substantially horizontally to the longitudinal direction of the tobacco rod and filled into the tobacco rod. . The width of the shredded tobacco is preferably 0.5 to 2.0 mm for filling the tobacco rod portion. The tobacco filler content in the tobacco rod is 200 to 800 mg/rod, preferably 250 to 600 mg/rod, in the case of a tobacco rod having a circumference of 22 mm and a length of 20 mm. Various kinds of tobacco can be used for the tobacco leaves used for producing the cut tobacco and the homogenized sheet. Examples include yellow, burley, oriental, landrace, other Nicotiana-tabacum varieties, Nicotiana-Rustica varieties, and mixtures thereof. As for the mixture, the above varieties can be appropriately blended and used so as to obtain the desired taste. Details of the tobacco varieties are disclosed in "Tobacco Encyclopedia, Tobacco Research Center, March 31, 2009". There are a number of conventional methods for producing the homogenized sheet, that is, methods for pulverizing tobacco leaves and processing them into homogenized sheets. The first method is a method of producing a papermaking sheet using a papermaking process. In the second method, an appropriate solvent such as water is mixed with pulverized tobacco leaves and homogenized, and then the homogenized product is thinly cast on a metal plate or metal plate belt and dried to form a cast sheet. It is a method of making. A third method is to prepare a rolled sheet by mixing pulverized tobacco leaves with an appropriate solvent such as water, homogenizing the mixture, and extruding the mixture into a sheet. The types of the homogenizing sheet are disclosed in detail in "Encyclopedia of Tobacco, Tobacco Research Center, March 31, 2009".

The above first tobacco filling is wrapped with wrapping paper so that it is on the inside to form a tobacco rod.

The second tobacco filling is composed of a plurality of concentrically arranged tobacco sheets. In the present specification, the term "concentrically arranged" means that all the tobacco sheets are arranged so that their centers are substantially at the same position. As used herein, the term "sheet" refers to a shape having a pair of substantially parallel main surfaces and side surfaces. The second packing is configured by concentrically winding a plurality of tobacco sheets in a direction perpendicular to the longitudinal direction of the non-combustion heating tobacco.
Examples of the sheet base material include tobacco materials such as tobacco powder, and tobacco materials are particularly preferable. It is preferably a tobacco sheet in which a component capable of generating flavor is supported on a base sheet of tobacco material, if necessary. A tobacco sheet generates an aerosol upon heating. Aerosol sources such as glycerin, propylene glycol, polyols such as 1,3-butanediol, and the like can be added as aerosol-forming substrates. The amount of such aerosol-generating substrate added is preferably 5 to 50% by weight, more preferably 15 to 25% by weight, based on the dry weight of the tobacco sheet.

A tobacco sheet as a raw material before being concentrically arranged will be described.
Tobacco sheets can be appropriately manufactured by known methods such as paper making, slurrying, and rolling. The homogenizing sheet described for the first tobacco filling can also be used.
In the case of papermaking, it can be manufactured by a method including the following steps. 1) Dry tobacco leaves are crushed and extracted with water to separate the water extract and residue. 2) Dry and concentrate the water extract under reduced pressure. 3) Pulp is added to the residue, fiberized with a refiner, and then paper is made. 4) A concentrated solution of the water extract is added to the paper sheet and dried to obtain a tobacco sheet. In this case, a step of removing some components such as nitrosamines may be added (see JP-T-2004-510422).
In the case of the slurry method, it can be produced by a method including the following steps. 1) Mix crushed tobacco leaves with water, pulp and binder. 2) The mixture is spread (cast) and dried. In this case, a step of removing some components such as nitrosamines by irradiating ultraviolet rays or X-rays to a slurry obtained by mixing water, pulp, binder, and crushed tobacco leaves may be added.

In addition, as described in WO 2014/104078, a non-woven tobacco sheet manufactured by a method including the following steps can also be used. 1) Mix powdered tobacco leaves and a binder. 2) The mixture is sandwiched between nonwoven fabrics. 3) The laminate is heat-sealed into a given shape to obtain a non-woven tobacco sheet.
The types of tobacco leaves used as raw materials in each of the above methods can be the same as those explained in the first filling.
Although the composition of the tobacco sheet is not particularly limited, for example, the content of the tobacco raw material (tobacco leaf) is preferably 50 to 95% by weight based on the total weight of the tobacco sheet. Further, the tobacco sheet may contain a binder, and examples of such binders include guar gum, xanthan gum, CMC (carboxymethylcellulose), CMC-Na (carboxymethylcellulose sodium salt), and the like. The amount of binder is preferably 1 to 20% by weight based on the total weight of the tobacco sheet. The tobacco sheet may further contain other additives. Examples of additives include fillers such as pulp. Although a plurality of tobacco sheets are used in this specification, such tobacco sheets may all have the same composition or physical properties, or part or all of the tobacco sheets may have different compositions or physical properties.

For the second tobacco filling, a plurality of tobacco sheets with different widths are prepared to form a laminated body in which the width decreases from the bottom to the top. can be manufactured by According to this manufacturing method, the plurality of tobacco sheets extend in the longitudinal direction and are arranged concentrically about the longitudinal axis. Also, a fitting portion extending in the longitudinal direction may be formed between the longitudinal axis and the innermost tobacco sheet.
In this manufacturing method, the laminate is preferably prepared so that a non-contact portion is formed between the adjacent tobacco sheets after roll-forming.
If there is a non-contact portion (gap) between the plurality of tobacco sheets that the tobacco sheets do not come into contact with, it is possible to ensure the flavor flow path and improve the delivery efficiency of the flavor component. On the other hand, since the heat from the heater can be transferred to the outer tobacco sheets through the contact portions of the plurality of tobacco sheets, high heat transfer efficiency can be ensured.

In order to provide non-contact portions between a plurality of tobacco sheets where the tobacco sheets do not come into contact, for example, embossed tobacco sheets are used, adjacent tobacco sheets are laminated without adhering their entire surfaces, and adjacent tobacco sheets Examples include a method of preparing a laminate by partially bonding and laminating adjacent tobacco sheets, or by laminating adjacent tobacco sheets by lightly bonding the entire surface or a portion thereof so that they can be peeled off after roll-forming. .
When preparing a tobacco rod portion including wrapping paper, the wrapping paper may be arranged at the bottommost portion of the laminate.
Alternatively, the fitting portion can be formed by placing a cylindrical dummy such as a mandrel on the uppermost portion of the laminate to form the second tobacco filling, and then removing the dummy.
Although the thickness of each tobacco sheet is not limited, it is preferably 200 to 600 μm in consideration of the balance between heat transfer efficiency and strength. The thickness of each tobacco sheet may be the same or different.
The number of tobacco sheets constituting the second tobacco filling is not particularly limited, but may be, for example, 2, 3, 4, 5, or 6 sheets.

The third tobacco filler consists of a single folded tobacco sheet. The sheet may be a so-called gathered sheet that has a length approximately equal to the longitudinal direction of the tobacco rod portion and is folded back multiple times horizontally to the longitudinal direction of the tobacco rod portion for filling. The thickness of the sheet is preferably 200 to 600 μm from the balance between heat transfer efficiency and strength.
As the sheet base material used for the third tobacco filling, the same material as that for the second tobacco filling can be used.

[rolling paper]
The structure of the wrapping paper is not particularly limited, and a general one can be used. For example, the base paper used for the wrapping paper can be cellulose fiber paper, more specifically hemp or wood or a mixture thereof. The "wrapping paper" used here is for wrapping the tobacco filler.

The blending ratio of the filler in the wrapping paper is not particularly limited, and is usually 1 to 50 wt%, preferably 5 to 45 wt%, more preferably 10 to 42 wt%, more preferably 20 to 40 wt%. is particularly preferred. For example, when determining the content of calcium carbonate, it can be determined by measuring the ash content, or by quantifying calcium ions after extraction.
Below the lower limit of the above range, the wrapping paper tends to scorch, and above the upper limit, the strength of the wrapping paper is greatly reduced, and the winding property may be deteriorated.

Various auxiliary agents other than the base paper and the filler may be added to the wrapping paper. For example, a water resistance improver can be added to improve the water resistance. Water resistance improvers include wet strength agents (WS agents) and sizing agents. Examples of wet strength agents include urea formaldehyde resins, melamine formaldehyde resins, polyamide epichlorohydrin (PAE), and the like. Examples of sizing agents include rosin soap, alkyl ketene dimer (AKD), alkenyl succinic anhydride (ASA), and highly saponified polyvinyl alcohol having a degree of saponification of 90% or more.
As an auxiliary agent, a paper strength agent may be added, and examples thereof include polyacrylamide, cationic starch, oxidized starch, CMC, polyamide epichlorohydrin resin, polyvinyl alcohol, and the like. In particular, it is known that the use of an extremely small amount of oxidized starch improves air permeability (Japanese Patent Application Laid-Open No. 2017-218699).
Moreover, the wrapping paper may be appropriately coated.

A coating agent may be added to at least one of the front and back sides of the wrapping paper. The coating agent is not particularly limited, but a coating agent capable of forming a film on the paper surface and reducing liquid permeability is preferred. For example, alginic acid and its salts (e.g. sodium salts), polysaccharides such as pectin, cellulose derivatives such as ethyl cellulose, methyl cellulose, carboxymethyl cellulose, nitrocellulose, starch and derivatives thereof (e.g. carboxymethyl starch, hydroxyalkyl starch and cationic starch). ether derivatives such as starch acetate, starch phosphate and ester derivatives such as starch octenylsuccinate).

The basis weight of the wrapping paper is usually 20-45 g/m ² , preferably 25-40 g/m ² . Within this range, moderate strength and winding properties can be maintained.
The air permeability of the wrapping paper is generally 0 to 120 Coresta units, preferably 5 to 100 Coresta units, more preferably 10 to 80 Coresta units. Within this range, moderate strength and smoking taste can be maintained.

<1-4. Mouthpiece section>
The configuration of the non-combustion heating cigarette 1 is not particularly limited, and may be a general configuration. For example, as shown in FIG. 3, it may have a cooling section 15 and a filter section 16, and these may be used in combination.

[Cooling part]
The structure of the cooling part is not particularly limited as long as it has a function of cooling mainstream tobacco smoke. In this case, the inside of the cylinder is a cavity, and the vapor containing the aerosol-generating substrate and the tobacco flavor component contacts the air in the cavity and is cooled.

As shown in FIG. 3, the non-combustion heating tobacco 1 has openings (not shown) for taking in air from the outside in the cooling part 15 and a part of the tipping paper 12 that can be covered with a lip release agent. may have Due to the presence of such openings, air flows into the cooling section 15 from the outside during use, and steam containing the aerosol-generating base material and the tobacco flavor component generated by heating the tobacco rod section is generated. , it can be liquefied by contact with air from the outside and the temperature is lowered, and the generation of aerosol can be promoted. As shown in FIG. 4, the cooling portion 15 has a plurality of openings 18 as described in the third aspect of "1-1. Winding portion" above. A plurality of openings 18 are arranged in the circumferential direction of the outer peripheral surface of the cooling portion 15 . The number of circumferential arrangement is not particularly limited, and may be two or more. Although the cooling part in FIG. 4 has a cylindrical shape with a cavity 17, it is not limited to this shape. Also, in FIG. 4, the boundary between the first area and the second area is omitted.
The pores preferably have a diameter of 100 to 1000 μm, more preferably 300 to 800 μm. The aperture is preferably substantially circular or substantially elliptical, and in the case of the substantially elliptical shape, the aforementioned diameter represents the major axis.

As shown in FIG. 4, the tip paper 12 and the lip release agent 13 may have holes so that the openings of the cooling part pass therethrough, or may not have holes, but they have a cooling effect. From the viewpoint of promotion, it is preferable to have holes.
In addition, as described in the third aspect of “1-1. ) is not particularly limited and may be two or more, but in this case, the circumferential arrangement is generally provided outside the lip contact area. , the circumferential arrangement that is the boundary between the first area and the second area is the circumferential arrangement closest to the mouthpiece end.
Also, the inside of the cooling portion may be filled with a sheet-shaped member such as paper, polymer film, or metal foil that has been gathered. In this case, the steam can be cooled using the specific heat of these members.
The height of the cooling part in the longitudinal direction is not particularly limited, but from the viewpoint of ensuring the cooling function, it is usually 5 to 40 mm, preferably 10 to 35 mm, more preferably 15 to 30 mm.

[Filter part]
The structure of the filter part 16 is not particularly limited as long as it has a function as a general filter. The single filament fineness and total fineness of the cellulose acetate tow are not particularly limited, but in the case of a filter portion with a circumference of 22 mm, the single filament fineness is preferably 5 to 12 g/9000 m, and the total fineness is preferably 12000 to 30000 g/9000 m. The cross-sectional shape of the fibers of the cellulose acetate tow may be a Y cross section or an R cross section. In the case of a filter filled with cellulose acetate tow, triacetin may be added in an amount of 5 to 10% by weight based on the weight of cellulose acetate tow in order to improve filter hardness.
Although the filter section 16 is composed of a single segment in FIG. 4, it may be composed of a plurality of segments. When it is composed of a plurality of segments, for example, a hollow segment such as a center hole is arranged on the upstream side (tobacco rod side), and the mouthpiece cross section is made of cellulose acetate tow as a downstream segment (user's mouth end side). A mode of arranging a filled acetate filter can be mentioned. According to this aspect, it is possible to prevent unnecessary loss of generated aerosol and improve the appearance of the non-combustion heating type cigarette. Further, from the viewpoint of change in sense of sucking response and gripping comfort, an acetate filter may be arranged on the upstream side and a hollow segment such as a center hole may be arranged on the downstream side. Note that a paper filter filled with sheet-like pulp paper may be used instead of the acetate filter.
In addition, in the production of the filter, adjustment of ventilation resistance and addition of additives (known adsorbents, perfumes, perfume-retaining materials, etc.) can be appropriately designed.
