  • An aerosol can be generated by heating the third formulation to a first temperature range of, for example, 180 to 280° C. by a heater (132), and the aerosol generated by the user's inhalation is inhaled through the user's mouth via the paper tube (54) and the filter (52). Even if heated to the first temperature range, the wrapping paper does not burn, but a portion of it may leak.
  • a heater 132
  • the heater pattern, sensing unit and control unit of the heater (132) are each electrically connected, and the battery (110) and control unit (120) are also electrically connected. It is preferable that the heater (132) wrap only the third segment (59) including the third preparation of the solid body, and not wrap the paper tube (54) or the filter (52).
