1. An aerosol generation device comprising:
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 to be inserted;
an opening/closing type cover disposed on the one surface of the case to open and close the opening, and configured to, when closing the opening, mechanically press an aerosol-generating substrate portion of the inserted aerosol-generating article; and
a heater configured to heat the inserted aerosol-generating article,
wherein the pressed aerosol-generating substrate portion comprises an upstream portion having a flat shape and a downstream portion having an inclined shape,
wherein the heater includes a first heater configured to heat one surface of the pressed aerosol-generating substrate portion and a second heater configured to heat the opposite surface of the one surface, and
wherein the opening/closing type cover is configured to, when closing the opening, mechanically press the aerosol-generating substrate portion of the inserted aerosol-generating article in a radius direction, the radius direction intersecting an axis in an insertion direction of the article insertion portion, so as to shorten the distance between a surface of the first heater where the one surface of the aerosol-generating substrate portion is heated and a surface of the second heater where the opposite side of the aerosol-generating substrate portion is heated.
