An aerosol generating apparatus includes a case including an insertion pipe for surrounding and supporting at least a portion of a cigarette and an extraction member that includes a disk for supporting a lower end of the cigarette, the extraction member being slidably installed on the case. The insertion pipe includes a step portion that is concaving away from an external surface to form an internal surface of the insertion pipe to allow mounting of the extraction member on the step portion, and based on the extraction member being removed from the case, the disk is configured to pressurize the lower end of the cigarette so that the cigarette is removed from the case.
