Abstract
Provided herein are a porous wick and a vaporizer and aerosol generation device including the same. The vaporizer according to some embodiments of the present disclosure includes a liquid reservoir configured to store an aerosol-generating substrate in a liquid state, a heating element configured to heat the stored aerosol-generating substrate to generate an aerosol, and a porous wick configured to deliver the stored aerosol-generating substrate to the heating element through a porous body and comprising a coating film formed on at least a part of a plurality of surfaces of the porous body. Since a coating film is formed on a surface not associated with a target transport path for a liquid, the liquid can be intensively transported along the target transport path.
