[0036] The through-hole 42 may be formed on one side of the body 10 opposite to the other side of the body 10 where the insertion space 12 is formed. The through-hole 42 may be cylindrical. However, the through-hole 42 is not limited thereto and may be formed in various sizes and shapes. The air inside the body 10 may be exchanged with the air outside through the through-hole 42.

[0037] Therefore, the pressure difference between the inside and outside of the aerosol generating device 100 can be improved.

[0038] The aerosol generating device 100 may further include a base 40 that forms the other side of the body 10 opposite to the one side of the body 10 where the insertion space 12 is formed.

[0043] The base 40 may include a foundation 46. The foundation 46 may extend from the base 40 and include a raised flat surface 460 on which a gasket 50 (described later) is seated. The foundation 46 may extend from a ground portion 45. A flow path for air flow may be formed between a side surface of the foundation 46 and the inner surface of the body 10. For example, a tapered flow path 82 may be formed between a side surface of the foundation 46 and the inner surface of the body 10.

[0044] The base 40 may be bent and extend in the length direction of the body 10 to form a curved surface. The base 40 may include a base side portion 48 extending in a rounded shape.

[0056] The cover 30 may include a rounded and extended cover side portion 36. The cover side portion 36 may be formed horizontally relative to the length direction of the body 10. A protrusion 362 may be formed on the inner side of the cover side portion 36. The protrusion 362 may be inserted into a groove 482 formed in the base 40, thereby allowing the cover 30 to be attached to the base 40. The protrusion 362 may be formed perpendicular to the cover side portion 36 toward the inner side of the body 10. The protrusion 362 may be formed perpendicular to the length direction of the body 10.
