Abstract: Provided is an aerosol generating device including a heater that heats an aerosol-generating material and a controller that controls power supplied to the heater. The controller may measure a resistance value of the heater by using at least one electrical characteristic associated with the heater, select any one power profile from among a plurality of pre-stored power profiles including values of power to be supplied to the heater, such that a temperature of the heater reaches a target temperature within a predetermined time from a time point at which power supply to the heater is initiated regardless of variation in the resistance value of the heater, and control power supplied to the heater according to the selected power profile.
