1. A vaporizer comprising:
a liquid storage configured to store an aerosol generating material;
an upper cap having a liquid inlet through which the aerosol generating material is introduced;
a lower cap coupled to the upper cap such that an aerosol generating space is formed between the lower cap and the upper cap;
a liquid delivery element arranged in the aerosol generating space and configured to absorb the aerosol generating material delivered from the liquid storage; and
a heating element configured to generate an aerosol by heating the aerosol generating material absorbed by the liquid delivery element,
wherein the lower cap includes a support groove for supporting at least part of the liquid delivery element, and an inner wall facing an end of the liquid delivery element,
wherein the upper cap includes a pressing portion configured to press the liquid delivery element toward the lower cap, and
wherein a ratio of a height of the liquid delivery element after being deformed by the pressing portion to a height of the liquid delivery element before being deformed by the pressing portion is in a range of 0.6 to 0.9.
