Abstract: There is provided a smoking material wrapper having micropores, wherein when the smoking material wrapper is divided into three regions at equal intervals from an upstream distal end based on the case where the smoking material wrapper is applied to a smoking article, an average porosity is greater as a region becomes closer to a downstream. According to an embodiment of the present disclosure, the micropores have a pore size of 10 μm to 50 μm, and are formed by a perforation method using plasma. The wrapper may maintain functionality as a wrapping material due to low visibility or the like, and may minimize a dilution ratio decreased due to burning of a smoking material unit while maintaining a basic dilution ratio when the smoking material wrapper is applied to a smoking article.

Abstract: An aerosol-generating device and an operation method thereof are disclosed. The aerosol-generating device of the disclosure includes a heater, a temperature sensor configured to detect the temperature of the heater, and a controller configured to monitor the temperature of the heater. The controller determines whether the temperature of the heater is equal to or higher than a predetermined first temperature while first power corresponding to preheating of the heater is supplied to the heater. When the temperature of the heater is equal to or higher than the first temperature, the controller changes power supplied to the heater to second power, which is lower than the first power. When the temperature of the heater is equal to or higher than a second temperature, which is higher than the first temperature, while the second power is supplied to the heater, the controller interrupts the supply of power to the heater.
