The thickness of the light transmitting portion 523 may be thinner than the thickness of the upper circumference 511 and the lower circumference 512 of the upper pipe 51. The light transmitting portion 523 may be formed by recessing the outer peripheral surface of the circumference 510 of the upper pipe 51 in a radial inward direction.

Accordingly, the transmittance of the laser beam (L) can be increased in the light transmitting portion 523, which is the area where welding is required.

The outer peripheral surface of the lower pipe 52 and the inner peripheral surface of the upper pipe 51 may overlap and support each other in the vertical direction.

a lower pipe disposed parallel to the lower side of the heating assembly and supporting the lower end of the heating assembly;
an upper pipe that supports the upper end of the heating assembly, extends downward, covers the circumference of the heating assembly, and includes a circumference that radially overlaps the circumference of the lower pipe;
In the overlapping portion, a light transmitting portion formed in one of the lower pipe and the upper pipe; and
An aerosol generating device comprising, in the overlapping portion, a light absorbing portion formed on the other of the lower pipe and the upper pipe and integrally coupled to an inner peripheral surface of the light transmitting portion. According to claim 1,
The upper pipe is,
Covering the outer peripheral surface of the heating assembly and the outer peripheral surface of the lower pipe,
The light absorbing part,
Formed in the lower pipe,
The light transmitting part,
An aerosol generating device formed on the upper pipe and surrounding the outer peripheral surface of the light absorbing part. According to clause 2,
The thickness of the light transmitting part is,
An aerosol generating device that is thinner than the circumference of the upper pipe formed around it. According to clause 3,
The light transmitting part,
An aerosol generating device formed by collapsing the outer peripheral surface of the upper pipe in a radial inward direction. According to claim 1,
The outer peripheral surface of the light absorbing part is,
An aerosol generating device that is fused to the inner peripheral surface of the light transmitting portion. According to clause 5,
The outer peripheral surface of the light absorbing part is
An aerosol generating device that is irradiated with a laser beam transmitted from the outside of the light transmitting portion and is melted and fused to the inner peripheral surface of the light transmitting portion. According to claim 1,

On the upper side of the heating assembly, the aerosol generating device further includes a pipe flange that protrudes in a radial inward direction from the inner peripheral surface of the upper pipe and supports the upper end of the heating assembly. According to clause 9,
The upper surface of the lower pipe is an aerosol generating device that supports the lower end of the heating assembly. According to clause 2,
The lower pipe is,
An aerosol generating device comprising a second insertion space that communicates with the first insertion space and extends downward from the first insertion space. According to claim 11,
The lower pipe is,
An aerosol generating device comprising a stick supporter that covers at least a portion of the bottom of the second insertion space. According to claim 12,
The lower pipe is,
An aerosol generating device surrounded by the stick supporter and including a connection passage communicating the second insertion space with an exterior of the lower pipe. According to clause 2,
An aerosol generating device in which the lower pipe and the upper pipe overlap and support each other in the vertical direction. According to claim 13,
The lower pipe is,
It protrudes in a radial outward direction from the peripheral peripheral surface and includes a first support rib facing the upper side,
The upper pipe is,
An aerosol generating device comprising a second support rib that protrudes in a radial inward direction from the circumferential inner peripheral surface, faces the lower side, and is coupled to the first support rib.
