1. An aerosol generating device comprising:
an aerosol generating material reservoir configured to store an aerosol generating material;
an atomizer configured to atomize the aerosol generating material into an aerosol and inject the aerosol into an atomization space;
an inflow passage configured to provide fluid communication between outside of the aerosol generating device and the atomization space;
a discharge passage which is surrounded by a passage wall and through which air introduced from the outside through the inflow passage and the aerosol are discharged out of the aerosol generating device; and
at least one convex surface configured to guide the aerosol to the outside of the aerosol generating device by Coanda effect, the at least one convex surface comprising a first convex surface protruding toward the discharge passage from the passage wall and being a curved shape,
wherein the atomization space is upstream of the first convex surface.
