Abstract: Provided is a serial-type planar heat-generating heater and a manufacturing method thereof. In particular, the present invention relates to a serial-type planar heat-generating heater, which is capable of maximizing the effect of heating by minimizing dead zones in which heat is not generated, achieving a maximum power output in a limited area, unlike in a parallel-type heater, and achieving high temperature uniformity in all of heat-generating surfaces of the planar heat-generating heater, is easy to design to control heating performance, and may be manufactured at low costs; and a manufacturing method thereof.

Abstract: Provided herein is an aerosol generation device with a reduced preheating time. The aerosol generation device according to some embodiments of the present disclosure includes a case including an opening formed in one surface, and an article insertion portion into which an aerosol-generating article including an aerosol-generating substrate is inserted, an opening/closing type cover which is disposed on the one surface of the case to open and close the opening, and a heater configured to heat the inserted aerosol-generating article. Here, the opening/closing type cover is configured to, when closing the opening, mechanically press an aerosol-generating substrate portion of the inserted aerosol-generating article so that the entire aerosol-generating substrate portion is rapidly heated, and in this way, a preheating time of the device may be reduced.
