Non-combustion smoking article having carbonaceous heat source

Abstract

There is provided a non-combustion smoking article including a carbonaceous heat source including a cylindrical outer wall and partitions disposed inside the outer wall, cross-sections of the partitions forming a grid, and having air passages defined by the partitions, and an aerosol generating section.

1 . A non-combustion smoking article comprising: a carbonaceous heat source comprising a cylindrical outer wall and partitions disposed inside the outer wall, cross-sections of the partitions forming a grid, and having air passages defined by the partitions; and an aerosol generating section. 
     
     
         2 . The non-combustion smoking article according to  claim 1 , wherein the carbonaceous heat source has a porosity of 50% or more. 
     
     
         3 . The non-combustion smoking article according to  claim 1 , wherein the carbonaceous heat source has a passage perimeter of 70 mm or more, the passage perimeter being a total of the lengths of the partitions facing the air passages. 
     
     
         4 . The non-combustion smoking article according to  claim 1 , wherein the carbonaceous heat source has a cross-sectional area of 9 mm 2  or more. 
     
     
         5 . The non-combustion smoking article according to  claim 1 , wherein the passage perimeter per cross-sectional area of the carbonaceous heat source is 4 mm/mm 2  or more. 
     
     
         6 . The non-combustion smoking article according to  claim 1 , wherein a carbon content of a heat source composition constituting the carbonaceous heat source ranges from 10 to 60% by weight.
