Abstract

A cigarette includes a tobacco rod, a front end plug positioned at a front end of the tobacco rod, a filter rod positioned at a rear end of the tobacco rod, and a wrapper surrounding the tobacco rod, the front end plug, and the filter rod and including at least one perforation formed in an area of the wrapper to allow air to flow to the inside of the wrapper.

What is claimed is: 
     
         1 . A cigarette comprising:
 a tobacco rod comprising a susceptor;   a front end plug positioned at a front end of the tobacco rod;   a filter rod comprising a plurality of segments positioned at a rear end of the tobacco rod; and   a wrapper surrounding the tobacco rod, the front end plug, and the filter rod and comprising at least one perforation formed in an area to introduce external air,   wherein the at least one perforation is formed in an area surrounding any one of the plurality of segments of the wrapper,   wherein, when the cigarette comprising the front end plug, the tobacco rod, and the filter rod is inserted into an aerosol generating device, the area in which the at least one perforation is formed is exposed out of the aerosol generating device.   
     
     
         2 . The cigarette of  claim 1 , wherein draw resistance of the front end plug is greater than draw resistance of each of the plurality of segments. 
     
     
         3 . The cigarette of  claim 2 , wherein the at least one perforation reduces draw resistance that is increased by the front end plug. 
     
     
         4 . The cigarette of  claim 1 , wherein each of the plurality of segments is a hollow filter. 
     
     
         5 . The cigarette of  claim 1 , wherein a diameter of the at least one perforation is 0.02 mm to 0.8 mm. 
     
     
         6 . The cigarette of  claim 1 , wherein the at least one perforation comprises a plurality of perforations,
 wherein the plurality of perforations are spaced apart from each other by a constant distance.   
     
     
         7 . The cigarette of  claim 1 , wherein the wrapper comprises an inner wrapper and an outer wrapper that surrounds the inner wrapper,
 wherein the at least one perforation is formed in the outer wrapper.   
     
     
         8 . The cigarette of  claim 1 , wherein the at least one perforation comprises a plurality of perforations arranged along a circumferential direction of the wrapper. 
     
     
         9 . An aerosol generating device comprising:
 a housing having a receiving space into which the cigarette according to  claim 1  is inserted;   an induction coil configured to form a magnetic field in the receiving space; and   a controller electrically connected to the induction coil to control power of a battery to be supplied to the induction coil.   
     
     
         10 . An aerosol generating system comprising:
 an aerosol generating device having a first receiving space into which the cigarette according to  claim 1  is inserted; and   a cradle having a second receiving space in which the aerosol generating device is accommodated.
