<1-1. Recommended part>

[The first area and the second area of the recommendation section]

As shown in FIG. 1 , the recommended portion in which the tobacco rod portion 10 and the mouthpiece portion 11 are recommended by the tip paper 12 is composed of a first area 12a and a second area 12b. . In addition, although not shown in FIG. 1, the tobacco rod part 10 is, as will be described later, a tobacco filling is recommended by the wrapper. In addition, the lip release agent 13 is coated on at least a part of the tip paper.

The first area 12a is, in the long axis direction of the unburned heated cigarette, an area including the inlet side end of the unburned heated cigarette, and the second area 12b is more recommended than the first area. It is an area located on the side of the negative tobacco rod part. The first region and the second region are adjacent regions.

In FIG. 1 , the lip release agent in the first region is a portion indicated by 13a, and the lip release agent in the second region is a portion indicated by 13b.

Note that the content of the lip release agent per unit area in the first region is simply referred to as “the amount of the lip release agent in the first region”, and the content of the lip release agent per unit area in the second region is simply referred to as “the amount of the lip release agent per unit area in the second region”. It is also called "the amount of the lip release agent in the 2nd area|region".

In conventional non-burning heated cigarettes, the lip release agent is usually coated on the entire surface of the tip paper, and the concentration of the lip release agent is changed within the surface, that is, so as to satisfy the above condition (A). It is not performed to apply a lip release agent. In this case, the lip release property, which is the purpose of application of the lip release agent, is achieved, but during use, a substance derived from the lip release agent generated by heating is generated from the entire surface of the tip paper.

On the other hand, when the lip release agent is coated so as to satisfy the above condition (A), the lip release agent in the first area not only achieves securing of lip release properties, but also increases the amount of the lip release agent in the second area to the first area. Since it is less than the amount of the lip release agent in the area, the amount of generation of the substance derived from the lip release agent at the time of use is reduced compared to the above-mentioned conventional non-burning heated tobacco. In addition, although the lip release agent is coated on at least a part of the tip paper, from the viewpoint of securing the lip release property, as the coated part of the lip release agent, a filter part to be described later that can be provided in the mouthpiece part is located immediately below. A preferred aspect is that at least a part of the tip paper area is coated, and a preferred aspect is that the tip paper area is coated over the entire surface.

Although the aspect in particular of a 1st area|region and a 2nd area|region is not restrict|limited, A especially preferable aspect is demonstrated below.

(1) first aspect

A first aspect of the first region and the second region is that the first region is a region in a longitudinal direction of the unburned heated cigarette from an inlet side end of the unburned heated cigarette to a position of 17 mm, and the second region includes: It is an aspect having the characteristic of being the area|region from the 17-mm position to the tobacco rod side end of the long-axis direction of a recommendation part.

In a general use aspect of the non-burning heated cigarette, if the lip release agent is coated on the first area, which is the area from the inlet side end of the unburned heated cigarette to a position of 17 mm, the smoker's lips and the unburned heated cigarette at the time of use Considering the area (also referred to as "lip contact area"), sufficient lip release properties can be ensured. In addition, by reducing the amount of the lip release agent applied in the second region, which is the region from the 17 mm position to the end of the tobacco rod side in the long axis direction of the recommended portion, the amount of material derived from the lip release agent during use can be reduced. there is.

The position from the inlet side end of the non-burning heated cigarette, which separates the first region and the second region, can be set to 17 mm from the above reasons, but it is possible to reduce the amount of substances derived from the lip release agent during use. From a viewpoint, it is preferable that it is 15 mm, It is more preferable that it is 13 mm, It is especially preferable that it is 10 mm. If the position is brought closer to the inlet end side more 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 is a region from the inlet side end of the unburned heated cigarette to a position 42.5% with respect to the length of the recommended portion in the longitudinal direction of the unburned heated cigarette, , the second area is an area from the 42.5% position to the end of the tobacco rod side in the long axis direction of the recommended portion.

In the same manner as in the first aspect, taking into consideration the general use aspect of the unburned heated cigarette, with respect to the length of the recommended portion in the long axis direction of the unburned heated cigarette, from the inhalation side end of the unburned heated cigarette to a position of 42.5% When the lip release agent is coated on the first region that is the region, sufficient lip release properties can be ensured, and the amount of substances derived from the lip release agent generated during use can be reduced.

The ratio from the inlet side end of the unburned heated cigarette to the length of the recommended portion in the long axis direction of the unburned heated cigarette that separates the first region from the second region may be 42.5% from the above reasons, but when using From the viewpoint of being able to reduce the amount of substances derived from the lip release agent in If the position is brought closer to the inlet end side more than this, it becomes difficult to secure the lip release property.

(3) third aspect

The mouthpiece part in the non-combustion heating type cigarette which is this embodiment may have a cooling part and a filter part. In a third aspect of the first region and the second region, which is an aspect that can be taken in this case, the cooling unit has a plurality of openings, and the plurality of openings are arranged in the circumferential direction of the outer peripheral surface of the cooling unit, and the first region This is an area from the inlet side end of the non-burning heated cigarette to the arrangement position of the perforation with respect to the length of the recommended portion in the long axis direction of the non-burning heated cigarette, and the second area is the long axis of the recommended portion from the arrangement position of the perforation It is an aspect having the characteristic of a region to the end of the tobacco rod side of the direction.

The opening in the cooling unit makes it possible to control the flow of air and smoke in the cooling unit or the filter unit by introducing dilution air from the opening to the inlet end side during use. Generally, the area|region on the inlet end side from the position where the opening hole is provided turns into a lip contact area|region. That is, if the lip release agent is coated in the region on the inlet end side from the opening position, sufficient lip release properties can be ensured. And as described in the first aspect, by reducing the amount of the lip release agent applied in the second region, the amount of the lip release agent-derived substance generated during use can be reduced. In particular, since the flow of air or smoke in the mouthpiece part changes with the opening position as a boundary, the temperature of the recommended part on the inlet end side rather than the open hole tends to decrease significantly more than the temperature of the recommended part on the tobacco rod side compared to the open hole. By reducing the content of the lip release agent in the recommended portion on the tobacco rod side from the opening position, the amount of the lip release agent-derived substance generated can be greatly reduced.

The said opening may be called a "ventilation opening" in this field|area.

Although the opening is arranged in the circumferential direction of the outer peripheral surface of the cooling unit (specifically, it is arranged on a surface perpendicular to the long axis direction of the non-burning heated tobacco in the cooling unit), the circumferential arrangement (“circumferential” arrangement".) The number is not particularly limited, and two or more may exist, but in this case, since it is generally outside the lip contact area that the circumferential arrangement is provided, the first area and the second area The circumferential arrangement serving as the boundary of the region is the circumferential arrangement closest to the mouth end.

The position of the opening is not particularly limited, but from the viewpoint of reducing the amount of lip release agent-derived substances generated during use, relative to the length of the recommended portion in the longitudinal direction of the non-burning heated cigarette, It is preferable to set it as 17 mm from the inlet side edge part, It is more preferable that it is 15 mm, It is more preferable that it is 13 mm, It is especially preferable that it is 10 mm.

In addition, the tip paper referred to herein refers to a sheet for connecting a plurality of segments in a non-burning heating type cigarette, such as connecting a tobacco rod part and a mouthpiece part, for example.

The manufacturing method of the tip paper is not particularly limited, and a general method can be applied. For example, in the case of a sun containing pulp as a main component, a long mesh paper machine, Among the papermaking processes by a papermaking machine, a fabric composite paper machine, etc., the method of arranging and homogenizing a base is mentioned. In addition, if necessary, a wet paper strength enhancer may be added to impart water resistance to the roll paper, or a sizing agent may be added to adjust the printing state of the roll paper. In addition, sulfuric acid bands, various anionic (anionic), cationic (cation), nonionic (nonionic) or amphoteric yield improvers, water freeness improvers, and intellectual power (紙力) ) additives for papermaking, such as an additive for papermaking, such as an enhancer, and additives for papermaking, such as a dye, a pH adjuster, an antifoaming agent, a pitch control agent, and a slime control agent.

As the pulp, in addition to being made from wood pulp such as softwood pulp and broadleaf pulp, flax pulp, hemp pulp, sisal pulp, esparto, etc. are generally It may be obtained by kneading and manufacturing non-wood pulp used for wrapping paper for smoking articles. In addition, as the kind of pulp, chemical pulp by kraft cooking method, acid/neutral/alkali sulfite cooking method, soda salt cooking method, etc., grand pulp, chemical grand pulp, thermomechanical pulp, etc. can be used.

The height of the tip paper 11 in the long axis direction is not particularly limited, but from the viewpoint of the delivery amount of the aerosol and production appropriateness, it is usually 15 mm or more, preferably 20 mm or more, and more preferably 25 mm or more. .

Although the air permeability in particular of the tip paper 11 is not restrict|limited, It is preferable that it is 10 Coresta units or less from a viewpoint of the delivery amount of an aerosol, and manufacturing appropriateness.

<1-2. Lip release agent>

The solid content of the lip release agent in this embodiment may be nitrocellulose (nitrocellulose), 100% of which may be nitrocellulose (nitrocellulose), and 100% of the solid content may be ethylcellulose, and these may be arbitrary in consideration of easiness of analysis and actual solid content. A mixture mixed in a proportion may be used. Moreover, the mixture which further contains components other than nitrocellulose and/or ethyl cellulose may be sufficient as the solid content of this lip release agent.

Conventionally, with a non-combustion heating type cigarette, the influence investigation on the taste etc. which made the lip release agent object was not performed. The present inventors prepare an unburned heated cigarette having a recommended portion coated with a lip release agent on the entire surface, and a non-burned heated cigarette that satisfies the above condition (A), and the content of TSNA contained in the unburned heated cigarette after use An experiment was conducted to compare the two. As a result, it was found that the non-burning heated cigarette having the recommended portion coated with the lip release agent on the entire surface contained more TSNA than the non-burning heated cigarette satisfying the condition (A). The present inventors considered this cause as follows.

As a typical component used for a lip release agent, nitrocellulose which is a nitrate ester of cellulose is mentioned. Usually, nitrocellulose is obtained by treating cellulose with a mixed acid of nitric acid and sulfuric acid. This nitrocellulose was decomposed by heating to generate nitric acid, and TSNA was generated when the nitric acid and the minor alkaloids in the tobacco material reacted. A non-burning heated cigarette having a recommended portion coated with a lip release agent on the entire surface has a wider area in which the lip release agent is heated than a non-burning heated cigarette having a recommended portion coated with a lip release agent on a part thereof. Therefore, since the heat of a heater was transmitted to the lip release agent directly or indirectly, and a part of the lip release agent was heated excessively, it is thought that the above results were brought.

In addition, TSNA is a generic name of tobacco-specific nitrosoamine, N'-nitrosononicotine (NNN), 4-(N-nitrosomethylamino)-1-(3-pyridyl)-1-view It is represented by tanone (NNK), N'-nitrosoanatabine (NAT), and N'-nitrosoanavacine (NAB).

When nitrocellulose is contained in the lip release agent, TSNA is generated as described above, but other than nitrocellulose, the lip release agent contains ingredients that may generate substances that have an undesirable effect on taste. . For example, ethyl cellulose which can be used for a lip release agent may cause an undesirable change in taste, etc.

The material in particular contained in the lip release agent in this embodiment is not restrict|limited, For example, although nitrocellulose, ethyl cellulose, and mixtures thereof, etc. are mentioned, From a viewpoint which can suppress generation|occurrence|production of TSNA, , which is particularly advantageous as a lip release agent containing nitrocellulose.

The lip release agent may contain components other than the said nitrocellulose and ethyl cellulose, For example, fillers, such as a calcium carbonate, can be used. A commercial item can be used for the component of these lip release agents.

The coating method in particular of the lip release agent to tip paper is not restrict|limited, A general coating method is applicable. The lip release agent can usually be used as an aqueous solution of 1.0 to 30.0 wt% or an ethyl acetate solution, and such an aqueous solution or ethyl acetate solution can be used in an embodiment of the present invention by using an appropriate printing method such as gravure printing, for example. It can be applied to the tip paper. A lip release agent is coated on the tip paper according to the embodiment of the present invention by a known means other than printing, for example, a method of applying an opaque ink by ink jet printing, a method of spraying or an impregnation method You can do it.

In addition, the lip release agent needs to be coated on at least a part of the outer surface in the first area of the tip paper, but may be coated on the inner surface. However, from the viewpoint of reducing the amount of substances derived from the lip release agent during use, it is preferable that the lip release agent is not coated on the inner surface of the tip paper.

[Content of lip release agent]

Content of a lip release agent satisfy|fills condition (A) as mentioned above.

By satisfying the condition (A), securing of lip release property is achieved, and the generation of substances derived from the lip release agent at the time of use is reduced, and the amount of substances having an undesirable effect on 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, but the lip release property is ensured and the origin of the lip release agent in use From the viewpoint of reducing the amount of substances generated, it is preferably 1/2 or less, more preferably 1/4 or less, particularly preferably 1/6 or less, and most preferably 1/8 or less.

The content of the lip release agent per unit area in the first region is not particularly limited as long as it is greater than the content of the lip release agent per unit area in the second region, but it is usually 0.20 μg/mm 2 or more and 1.00 μg/mm 2 or less, preferably Preferably, it is 0.25 μg/mm 2 or more and 0.75 μg/mm 2 or less.

The first tobacco filling described above is recommended by the wrapping paper so that it is inside to form a tobacco rod portion.

A 2nd tobacco filling is comprised from the some tobacco sheet arrange|positioned concentrically. In this specification, "arranged concentrically" means that it is arrange|positioned so that the center of all the tobacco sheets may be in substantially the same position. As used herein, the term "sheet" refers to a shape having a pair of substantially parallel main surfaces and side surfaces. A 2nd filler is comprised by winding several tobacco sheets concentrically in the direction orthogonal to the longitudinal direction of a non-burning heating type cigarette.

As a sheet base material, although tobacco materials, such as tobacco powder, etc. are mentioned, for example, Tobacco material is especially preferable. It is preferable that it is the tobacco sheet which supported the component which can generate|occur|produce flavor on the base material sheet of a tobacco material as needed. A tobacco sheet generates an aerosol with heating. An aerosol source such as a polyol such as glycerin, propylene glycol or 1,3-butanediol may be added as an aerosol-generating substrate. 5 to 50 weight% is preferable with respect to the dry weight of the tobacco sheet, and, as for the addition amount of such aerosol generating base material, 15 to 25 weight% is more preferable.

A cigarette sheet as a material before being arranged concentrically will be described.

A tobacco sheet can be suitably manufactured by well-known methods, such as sheet making, a slurry, and rolling. It is also possible to use the leveling sheet described in the first tobacco filler.

In the case of sheet metal, it can be manufactured by a method including the following steps. 1) Dried tobacco leaves are crushed, extracted with water, and separated into water extract and residue. 2) The water extract is dried under reduced pressure and concentrated. 3) Pulp is added to the residue, and it is made into fibers with a refiner, and then papermaking is performed. 4) Add the concentrate of water extract to the paper-made sheet and dry it to make a tobacco sheet. In this case, a step of removing some components such as nitrosamine may be added (refer to Japanese Patent Application Laid-Open No. 2004-510422).

In the case of a slurry method, it can manufacture by the method including the following processes. 1) Mix water, pulp and binder with crushed tobacco leaves. 2) Spread the mixture thinly (cast it) and dry it. In this case, you may add the process of removing some components, such as a nitrosamine, by irradiating ultraviolet rays or X-rays with respect to the slurry which mixed water, pulp, a binder, and crushed tobacco leaves.

In addition, as described in International Publication No. 2014/104078, it is also possible to use a non-woven cigarette sheet manufactured according to a method including the following steps. 1) Mix granular tobacco leaves and binder. 2) The mixture is sandwiched by a non-woven fabric. 3) The said laminate is shape|molded into a fixed shape by heat welding, and the nonwoven fabric form tobacco sheet is obtained.

As for the kind of tobacco leaf of a raw material used by each said method, the thing similar to what was demonstrated with the 1st packing can be used.

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 the binder include guar gum, xanthan gum, CMC (carboxymethyl cellulose), CMC-Na (sodium salt of carboxymethyl cellulose), and the like. As an amount of binder, it is preferable that it is 1 to 20 weight% with respect to the total weight of a tobacco sheet. The tobacco sheet may further contain other additives. As an additive, fillers, such as pulp, are mentioned, for example. Although a plurality of tobacco sheets are used in this specification, all of these tobacco sheets may have the same composition or physical properties, or some or all of the tobacco sheets may have different compositions or physical properties.

The second tobacco filler prepares a plurality of tobacco sheets having different widths, prepares a laminate in which the width becomes smaller from the bottom to the top, and a laminate is prepared, and this is It can be manufactured by passing it through the 管) and hoisting (卷上) molding. According to this manufacturing method, while the some tobacco sheet is extended in a longitudinal direction, it will be arrange|positioned concentrically centering on the longitudinal axis. Moreover, the fitting part extended in the longitudinal direction may be formed between the longitudinal axis|shaft and the tobacco sheet of an innermost layer.

In this manufacturing method, it is preferable that a laminated body is prepared so that a non-contact part may be formed between the said tobacco sheets adjacent after roll-up shaping|molding.

If there exists a non-contact part (gap) which the said tobacco sheet does not contact between several tobacco sheets, a flavor flow path can be ensured and delivery efficiency of a flavor component can be improved. On the other hand, since heat from the heater can be transferred to the tobacco sheet on the outside through the contact portions of the plurality of tobacco sheets, high heat transfer efficiency can be ensured.

In order to provide a non-contact portion where the tobacco sheets do not contact between a plurality of tobacco sheets, for example, embossed tobacco sheets are used, and the entire surface of adjacent tobacco sheets is not adhered. A method of preparing a laminate by laminating by adhering and laminating a part of adjacent tobacco sheets without lamination, or by adhering and laminating the entire surface or a part of adjacent tobacco sheets with hardness so as to be peeled off after roll-up molding can be heard

When preparing the tobacco rod part containing the wrapping paper, you may arrange|position the said wrapping paper in the lowest part of a laminated body.

Moreover, after mounting cylindrical piles, such as a mandrel, on the outermost part of a laminated body to form a 2nd tobacco filling, a fitting part can also be formed by removing this pile.

Although the thickness of each tobacco sheet is not restrict|limited, From the balance of heat transfer efficiency and intensity|strength, 200-600 micrometers is preferable. The thickness of each tobacco sheet may be the same or different.

Although the number of sheets in particular of the tobacco sheet which comprises a 2nd tobacco filling is not restrict|limited, For example, 2 sheets, 3 sheets, 4 sheets, 5 sheets, or 6 sheets is mentioned.

The third tobacco filler is composed of a single folded tobacco sheet. The sheet may be a so-called gather sheet, which has a length about the same as that of the tobacco rod portion in the longitudinal direction, and is folded and filled multiple times horizontally in the longitudinal direction of the tobacco rod portion. As for the thickness of this sheet|seat, 200-600 micrometers is preferable from the balance of heat transfer efficiency and intensity|strength.

The sheet base material used for the third tobacco filler may be the same as that of the second tobacco filler.

[Kwon Ji]

The configuration of the wrapper is not particularly limited, and a general one can be used. For example, as a base paper used for wrapping paper, a cellulose fiber paper can be used, More specifically, hemp or wood, or a mixture thereof is mentioned. In addition, the "wrap paper" referred to here is for recommending a tobacco filling.

The wrapping paper may contain filler, and the type of filler is not limited. Metal carbonates such as calcium carbonate and magnesium carbonate, metal oxides such as titanium oxide and aluminum oxide, and metals such as barium sulfate and calcium sulfate Metal sulfides such as sulfate and zinc sulfide, quartz, kaolin, talc (talc), diatomaceous earth, gypsum, etc., in particular, include calcium carbonate from the viewpoint of improving whiteness or opacity and increasing heating rate, It is preferable to have

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%, and particularly preferably 20 to 40 wt%. In addition, for example, when calculating|requiring content of calcium carbonate, it can obtain|require by ash content measurement or by quantifying a calcium ion after extraction.

Various adjuvants other than the base paper and filler may be added to the wrapping paper, and, for example, in order to improve water resistance, a water resistance improving agent can be added. The water resistance improver includes a wet strength enhancer (manufactured by WS) and a sizing agent. Examples of the wet-branching agent include urea formaldehyde resin, melamine formaldehyde resin, polyamide epichlorhydrin (PAE), and the like. Examples of the sizing agent 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 the auxiliary agent, an intellectual strength enhancer may be added, and examples thereof include polyacrylamide, cationic starch, oxidized starch, CMC, polyamide epichlorohydrin resin, and polyvinyl alcohol. In particular, regarding oxidized starch, it is known that air permeability is improved by using a very small amount (Japanese Patent Application Laid-Open No. 2017-218699).

In addition, the wrapping paper may be suitably coated.

A coating agent may be added to at least one surface among two surfaces of the surface and the back surface to a wrapper. Although there is no restriction|limiting in particular as a coating agent, A coating agent which can form a film|membrane on the surface of paper and reduce the permeability of a liquid is preferable. For example, alginic acid and its salts (eg sodium salt), polysaccharides such as pectin, cellulose derivatives such as ethyl cellulose, methyl cellulose, carboxymethyl cellulose, nitrocellulose, starch or its derivatives (eg, ether derivatives such as carboxymethyl starch, hydroxyalkyl starch and cationic starch, ester derivatives such as starch acetate, starch phosphate and starch octenylsuccinate).

The basis weight of the wrapper is usually 20 to 45 g/m 2 , and preferably 25 to 40 g/m 2 . If it exists in this range, moderate intensity|strength and hoisting property can be maintained.

The air permeability of the wrapping paper is usually 0 to 120 Coresta units, preferably 5 to 100 Coresta units, and more preferably 10 to 80 Coresta units. If it is in this range, moderate intensity|strength and taste can be maintained.

[Cooling part]

The configuration of the cooling unit will not be particularly limited as long as it has a function of cooling mainstream tobacco smoke, and examples of the cooling unit include those obtained by processing Fuji paper into a cylindrical shape. In this case, the inside of the cylindrical shape is a cavity, and the vapor comprising the aerosol-generating substrate and the tobacco flavor component is cooled by contact with the air in the cavity.

As shown in FIG. 3 , the non-burning heated cigarette 1 blows air from the outside into the cooling unit 15 and a part of the tip paper 12 that can be covered with the lip release agent. ) may have an opening (not shown) for Due to the presence of such an opening, air flows into the inside of the cooling unit 15 from the outside during use, and the vapor containing the aerosol-generating substrate and tobacco flavor component generated by heating the tobacco rod is in contact with the air from the outside. By lowering the temperature, it can liquefy and promote the generation of an aerosol. As shown in FIG. 4 , the cooling unit 15 further includes the above-described "1-1. As described in the third aspect of "recommended portion", when the cooling unit 15 has a plurality of openings 18 , the plurality of openings 18 are formed around the outer peripheral surface of the cooling unit 15 . placed in the direction The number of arrangement|positioning in particular in the circumferential direction is not restrict|limited, Two or more may exist. In addition, although the cooling part of FIG. 4 is making it into the cylindrical shape which has the cavity 17, it is not limited to the shape. In addition, in FIG. 4, the boundary between a 1st area|region and a 2nd area|region is abbreviate|omitted.

It is preferable that a diameter is 100-1000 micrometers, and, as for an opening, it is more preferable that it is 300-800 micrometers. It is preferable that an opening hole has a substantially circular or substantially elliptical shape, and the said diameter in case of a substantially elliptical shape represents a major axis.

As shown in Fig. 4, with respect to the tip paper 12 and the lip release agent 13, a hole may or may not be provided so that the opening of the cooling unit penetrates, but from the viewpoint of promoting the cooling effect. , it is preferable to have a hole.

In addition, the above-mentioned "1-1. As described in the third aspect of “recommended portion”, the openings are arranged in the circumferential direction of the outer peripheral surface of the cooling unit, but the number of arrangement in the circumferential direction (also referred to as “circumferential arrangement”) is not particularly limited, and two In this case, although the circumferential arrangement is generally provided outside the lip contact region, the circumferential arrangement serving as the boundary between the first region and the second region is the most at the mouth end. It should be arranged in a near-circumferential arrangement.

Moreover, you may fill the inside of a cooling part what processed the sheet-like member, such as paper, a polymer film, or metal foil, to gather. In this case, the vapor may be cooled by using the specific heat of these members.

Although the height in particular of a long-axis direction of a cooling part is not restrict|limited, From a viewpoint of ensuring a cooling function, it is 5-40 mm normally, it is preferable that it is 10-35 mm, It is more preferable that it is 15-30 mm.

[Filter part]

The structure of the filter part 16 will not be restrict|limited in particular, as long as it has a function as a general filter, For example, what processed the cellulose acetate tow into column shape is mentioned. The single yarn fineness and total fineness of the cellulose acetate tow are not particularly limited, but in the case of a filter part with a circumference of 22 mm, the single yarn fineness is 5 to 12 g/9000 m, and the total fineness is 12000 to It is preferable that it is 30000g/9000m. The cross-sectional shape of the fibers of the cellulose acetate tow may be a Y-section or an R-section. In the case of a filter filled with cellulose acetate tow, in order to improve filter hardness, 5 to 10% by weight of triacetin may be added based on the weight of the cellulose acetate tow.

In Fig. 4, the filter unit 16 is composed of a single segment, but 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 as a segment on the downstream side (intake end side of the user), the inlet section is cellulose acetate One example is the arrangement of an acetate filter filled with tow. According to this aspect, while preventing useless loss of the aerosol to generate|occur|produce, the external appearance of a non-combustion heating type cigarette can be made favorable. Moreover, an aspect which arrange|positions an acetate filter on an upstream side, and arrange|positions hollow segments, such as a center hole, may be sufficient from a viewpoint of the sensory change of inhalation|suction feeling or a bite feeling. Moreover, instead of the said acetate filter, the aspect using the paper filter filled with sheet-like pulp paper may be sufficient.

Moreover, in manufacture of a filter, adjustment of ventilation resistance and addition of additives (a well-known adsorbent, a fragrance|flavor, a fragrance|flavor holding material, etc.) can be designed suitably.
