Tobacco sheet for non-combustion heating-type flavor inhaler, non-combustion heating-type flavor inhaler, and non-combustion heating-type flavor inhalation system

Abstract

This tobacco sheet for a non-combustion heating-type flavor inhaler contains a tobacco powder having a cumulative 90% particle diameter (D90) of at least 200 μm in a volume-based particle size distribution as measured by a dry laser diffraction method.

1 . A tobacco sheet for a non-combustion heating-type flavor inhaler, comprising a tobacco powder with a cumulative 90% particle diameter (D90) of 200 μm or more in a volume-based particle size distribution as measured by a dry laser diffraction method,
 wherein at least one surface has an arithmetic mean surface roughness Sa in the range of 5 to 30 μm. 
 
     
     
         2 . (canceled) 
     
     
         3 . The sheet according to  claim 1 , which is a press-formed sheet. 
     
     
         4 . The sheet according to  claim 1 , comprising a cellulose derivative with a degree of substitution of 0.65 or more. 
     
     
         5 . The sheet according to  claim 4 , wherein the degree of substitution is 0.7 or more. 
     
     
         6 . A non-combustion heating-type flavor inhaler comprising a tobacco-containing segment containing the tobacco sheet for a non-combustion heating-type flavor inhaler according to  claim 1 . 
     
     
         7 . A non-combustion heating-type flavor inhaling system comprising:
 the non-combustion heating-type flavor inhaler according to claim  6 ; and   a heating device for heating the tobacco-containing segment.
