According to an embodiment, the camera module  212  may be disposed on the bracket  232  and may be a rear camera module (e.g., the camera module  212  of  FIG.  3   ) capable of acquiring an image of a subject located in the rear (e.g., −Z direction) of the electronic device  200 . According to an embodiment, at least a part of the camera module  212  may be exposed to the outside of the electronic device  200  through an opening  282  disposed on the rear plate  280 . 
     Although the electronic device  200  illustrated in  FIG.  2    to  FIG.  4    has a bar type or plate type exterior, the disclosure is not limited thereto. For example, the illustrated electronic device may be a rollable electronic device or a foldable electronic device. The term “rollable electronic device” may refer to an electronic device which includes a display (e.g., the display  220  of  FIG.  4   ) capable of bending deformation such that at least a portion thereof is wound or rolled or accommodated in a housing (e.g., the housing  210  of  FIG.  2   ).

The shielding structure  10  may shield the electronic component (e.g., the first component  401  of  FIG.  5   ) disposed on the printed circuit board  240  and may diffuse heat or electromagnetic waves generated from the electronic component (e.g., the first component  401  of  FIG.  5   ). According to various embodiments, the shielding structure (e.g., the shielding structure  10  of  FIG.  5   ) may be provided by the printed circuit board  240 , a shield can (e.g., the shield can  420  of  FIG.  5   ), and/or a nanofiber film (e.g., the nanofiber film  500  of  FIG.  5   ), which are combined, or the arrangement relationship thereof. 
     In the following description of the disclosure, the shielding structure  10  described above will be described with reference to the drawings. 
       FIG.  5    is a cross-sectional view illustrating a shielding structure according to various embodiments. 
     Referring to  FIG.  5   , the shielding structure  10  may include a circuit board  400 , a first component  401  disposed on the circuit board, a shield can  420  disposed on the circuit board to surround at least a part of the first component  401 , a nanofiber film  500  disposed on the shield can  420 , and a support member  300  disposed adjacent to the nanofiber film  500 . 
     The circuit board  400  of  FIG.  5    may be the same as or similar to the printed circuit board  240  of  FIG.  4    in whole or in part. The support member  300  of  FIG.  5    may be the same as or similar to the above-described bracket  232  or rear case  260  of  FIG.  4    in whole or in part. 
     According to various embodiments, the shield can  420  may be disposed around the first component  401 . In an embodiment, the shield can  420  may be a medium capable of transmitting electromagnetic waves (e.g., noise) generated by the first component  401 . For example, the electromagnetic wave generated by the first component  401  may be transmitted to the circuit board  400  via the shield can  420 . For example, the shield can  420  may be connected to the circuit board  400  having a grounding function, and absorb the electromagnetic waves generated by the first component  401  and/or a second component  402 . In an embodiment, the second component  402  and the first component  401  may be arranged on the circuit board  400  in parallel to each other, and the shield can  420  may be disposed to surround both the second component  402  and the first component  401 . In an embodiment, the shield can  420  may be arranged to surround the first component  401  to transmit the heat radiated from the first component  401  to the outside (e.g., the bracket  232  of  FIG.  4   ). In the following description, the first component  401  and/or the second component  402  may refer, for example, and without limitation, to an application processor (AP) and/or a memory (e.g., the memory  130  of  FIG.  1   ). 
     According to an embodiment, the shield can  420  may be made of a highly electrically conductive and/or thermally conductive material. For example, the shield can  420  may be made of a metal material. As the shield can  420  is made of a metal material, the heat or electromagnetic waves radiated from the first component  401  can be efficiently dispersed. According to various embodiments, the shield can  420  may include an opening  421 . Heat may be efficiently diffused to the outside of the shield can  420  through the opening  421 . In an embodiment, the opening  421  may be disposed to correspond to the position of the first component  401 . For example, when the shielding structure  10  is viewed from the side (y-axis direction), the positions of the first component  401  and the opening  421  on the x-axis may correspond to each other. 
     According to various embodiments, the nanofiber film  500  may be arranged on the upper position (−z-axis direction) of the shield can  420 . For example, at least a part of the nanofiber film  500  may be arranged to shield the opening  421 . 
     According to various embodiments, a filling member  499  may be disposed on the first component  401 . For example, the filling member  499  may be disposed at a position corresponding to the opening  421  of the shield can  420 . In addition, the filling member  499  may be disposed between the first component  401  and the nanofiber film  500 . In an embodiment, the heat radiated from the first component  401  may be transferred to the nanofiber film  500  via the filling member  499 . According to an embodiment, the filling member  499  may be comprised of at least one of materials in a liquid state, a solid state, and a semi-solid state. The filling member  499  may be made of a material having high thermal conductivity. In an example, the filling member  499  may be a thermal interface material (TIM). 
     According to various embodiments, the nanofiber film  500  may transfer the heat transferred from the shield can  420  to the outside (e.g., the support member  300 ). The nanofiber film  500  may provide an electrical travel route for transferred the electromagnetic waves transferred from the shielded can  420 . For example, the nanofiber film  500  may transfer electromagnetic waves in the horizontal direction (x-axis direction) on the shield can  420 . In another example, the nanofiber film  500  may transfer electromagnetic waves from the shield can  420  disposed on one side (−x-axis direction) of the opening  421  to the shield can  420  disposed on the other side (+x-axis direction) of the opening  421 . 
     According to various embodiments, the nanofiber film  500  may be disposed adjacent to another configuration (e.g., the bracket  232  in  FIG.  4   ) in the electronic device (e.g., the electronic device  200  in  FIG.  4   ). For example, the nanofiber film  500  may be disposed adjacent to the support member  300 . In another example, the support member  300  may be disposed on the upper position (−z-axis direction) of the nanofiber film  500 . Accordingly, the heat generated by the nanofiber film  500  may be diffused via the support member  300 . The nanofiber film  500  may be disposed to be in contact with the support member  300 , but it is not essential and may be disposed to be spaced a predetermined (e.g., specified) distance apart therefrom. In an embodiment, the nanofiber film  500  may be disposed adjacent to a member for heat dispersion (e.g., the heat diffusion member  320 - 1  in  FIG.  9   ). For example, the heat diffusion member (e.g., the heat diffusion member  320 - 1  in  FIG.  9   ) in the embodiments described in greater detail below may include at least one of a water-cooling heat diffusion member (vapor chamber), a heat pipe, a heat sink, a heat spreader, a Cu plate, a graphite sheet, and/or graphene. The heat diffusion member (e.g., the heat diffusion member  320 - 1  in  FIG.  9   ) may be accommodated in the support member  300  or may be disposed between the nanofiber film  500  and the support member  300  to face each other. In the shielding structure  10  according to various embodiments, the arrangement relationship between the nanofiber film  500  and the internal elements of the electronic device (e.g., the electronic device  200  in  FIG.  4   ) will be described in detail greater detail below with reference to  FIG.  9    to  FIG.  13   . 
     According to various embodiments, the nanofiber film  500  can be compressed. For example, the shielding structure  10  needs to have a small height with respect to the vertical direction (−z-axis direction) for the space efficiency in the electronic device (e.g., the electronic device  200  of  FIGS.  2  and  3   ), and to this end, the nanofiber film  500  may be made of a compressible material. 
       FIG.  6    is an exploded perspective view illustrating an example stacked structure of a nanofiber film  500  according to various embodiments.  FIG.  7    is a diagram illustrating an enlarged nanofiber film  500  according to various embodiments. 
     Referring to  FIG.  6    and  FIG.  7   , the nanofiber film  500  may include a first layer  510 , a second layer  520  disposed on the first layer, and a third layer  530  disposed on the second layer. For example, the nanofiber film  500  may be described as being formed by sequentially laminating the third layer  530  to the first layer  510 . Since the nanofiber film  500  of  FIG.  6    may be the same as or similar to the nanofiber film  500  of  FIG.  5    in whole or in part, the redundant description may not be repeated. 
     According to various embodiments, the nanofiber film  500  may be formed by laminating a plurality of layers having different densities. In an embodiment, all or some of the first to third layers  510 ,  520 , and  530  may have different or the same densities. For example, the first layer  510  and the third layer  530  may be configured to have a higher density than the second layer  520  disposed between the first layer  510  and the third layer  530 . 
     According to various embodiments, the nanofibers of each layer  510 ,  520 , and  530  may have different thicknesses depending on each layer  510 ,  520 , and  530 , or may have substantially the same or similar thickness. For example, the thickness of the nanofibers  510   a  and  530   a  of the first layer  510  and the third layer  530  may be configured thinner than the thickness of the nanofiber  520   a  of the second layer  520 . In another example, the thickness of the nanofiber  520   a  of the second layer  520  may be larger than the thickness of the nanofibers  510   a  and/or  530   a  of the first layer  510  and/or the third layer  530 . In an embodiment, the thickness of the nanofibers  510   a  and/or  530   a  of the first layer  510  and/or the third layer  530  may be configured to be about 4-6 micrometers. The thickness of the nanofiber  520   a  of the second layer  520  may be configured to be about 17-22 micrometers. 
     According to various embodiments, the air permeability of all or some of each layer  510 ,  520 , and  530  of the nanofiber film  500  may be substantially the same as or different from each other. For example, the air permeability of the first layer  510  and the third layer  530  may be smaller than the air permeability of the second layer  520 . For example, the first to third layers  510 ,  520 , and  530  of the nanofiber film  500  may be distinguished by the density, the thickness of the nanofibers  510   a ,  520   a , and  530   a  of the layers, and/or the air permeability. In an embodiment, the first layer  510  and/or the third layer  530  may have an air permeability of about 20-25 cm 3 /cm 2 /s. The second layer  520  may have an air permeability of about 210-220 cm 3 /cm 2 /s. In an embodiment, as the low-density layer (the second layer  520 ) is disposed between the high-density layers (the first layer  510  and/or the third layer  530 ), the nanofiber film  500  may facilitate physical compression and restoration. As the high-density layer (the first layer  510  or the third layer  530 ) is arranged on the outer surface of the nanofiber film  500 , the shielding performance may be improved by having low surface resistance and horizontal electrical resistance. As the low-density layer (the second layer  520 ) is arranged in the middle of the nanofiber film  500 , it has low electrical resistance in the vertical direction and the shielding performance may be improved. 
     According to various embodiments, since the second layer  520  arranged in the middle of the nanofiber film  500  may have a lower density than the first layer  510  and/or the third layer  530  arranged on the outer surface of the nanofiber film  500 , when the nanofiber film  500  is compressed, the second layer  520  may be deformed more than the first layer  510  and/or the third layer  530 . 
     According to various embodiments, a conductive material may be plated on the nanofiber film  500 . In an embodiment, the conductive material may be a metal material. For example, the conductive material may include at least one or more of copper (Cu), zinc (Zn), aluminum (Al) or silver (Ag). 
     According to various embodiments, an adhesive material may be disposed on the first layer  510 . In an embodiment, the adhesive material may include pressure-sensitive adhesive (PSA). The adhesive material may be configured in solid state, liquid state, or semi-solid state. In an embodiment, the adhesive material may be coated on the first layer  510 . In an embodiment, as the adhesive material is disposed on the first layer  510 , as will be described in greater detail below, the thermal resistance between the first layer  510  and the support member (e.g., the support member  300  in  FIG.  5   ) or the heat diffusion member (e.g., the heat diffusion member  320 - 1  in  FIG.  9   ) may be reduced. 
     According to various embodiments, a conductive adhesive material may be disposed on the third layer  530 . In an embodiment, the conductive adhesive material may include a conductive filler. For example, the conductive adhesive material may be a pressure-sensitive adhesive (PSA) mixed with a conductive filler. In an embodiment, the conductive filler may include a carbon-based (C) material. For example, a carbon-based (C) conductive filler may include carbon black, carbon fiber and/or graphite. In an embodiment, the conductive filler may include a metal-based material. For example, a metal-based conductive filler may include all or some of silver (Ag), copper (Cu), nickel (Ni), zinc oxide (ZnO), tin oxide (SnO), aluminum (Al), and/or stainless steel. In an embodiment, the conductive filler may be made of synthetic fibers. However, this is merely an example and conductive fillers made of various materials may be used. 
       FIGS.  8 A and  8 B  are diagrams illustrating a conductive material plated on a nanofiber film according to various embodiments.  FIG.  8 A  illustrates a plating direction of the first layer and/or the third layer according to various embodiments.  FIG.  8 B  illustrates a plating direction of the second layer according to various embodiments. 
     Referring to  FIGS.  8 A and  8 B , a conductive material may be plated on the nanofiber film  500 . The description of the nanofiber film  500  in the above-described embodiment may be applicable to the nanofiber film  500  of  FIGS.  8 A and  8 B . 
     According to various embodiments, as described above, all or part of the first layer  510 , the second layer  520 , and the third layer  530  may have the same or different fiber densities. Accordingly, the plating direction of the conductive material may correspond to the respective fiber densities of the first layer  510  to the third layer  530  or the thickness of the nanofibers thereof. 
     For example, the second layer  520  may have a relatively low fiber density as compared to the first layer  510  and/or the third layer  530 , and accordingly, in the second layer  520 , a plating solution may be arranged so as to be superior in the vertical direction as compared with the first layer  510  and/or the third layer  530 . In another example, the first layer  510  and/or the third layer  530  may have a relatively high fiber density as compared to the second layer  520 , and accordingly, in the first layer  510  and/or the third layer  530 , a plating solution may be arranged so as to be superior in the horizontal direction as compared with the second layer  520   
     According to various embodiments, each layer  510 ,  520 , and  530  of the nanofiber film  500  may have different electrical resistance depending on the direction. In an embodiment, the electrical resistance of each layer  510 ,  520 , and  530  may correspond to the fiber density of each layer  510 ,  520 , and  530  or may correspond to the thickness of the nanofibers of each layer  510 ,  520 , and  530 . For example, as described above, since the first layer  510  and/or the third layer  530  have a relatively thin fiber thickness compared to the second layer  520 , as compared with the second layer  520 , the electric material is plated in the horizontal direction (x-axis direction) so that the electrical resistance is lower in the horizontal direction (x-axis direction). In another example, since the second layer  520  have a relatively thick fiber thickness compared to the first layer  510  and/or the third layer  530 , the second layer  520  may have a relatively low electrical resistance in the vertical direction (z-axis direction) as compared to the first layer  510  and/or the third layer  530 . For example, it can be expressed that the first layer  510  and/or the third layer  530  has better conductivity in the horizontal direction (x-axis direction) as compared with the second layer  520 , and the second layer  520  has better conductivity in the vertical direction (z-axis direction) as compared with the first layer  510  and/or the third layer  530 . Accordingly, the first layer  510  and/or the third layer  530  may transfer the electromagnetic wave generated by the first component  401  in the horizontal direction (x-axis direction), and the second layer  520  may provide an electrical movement path in the vertical direction (z-axis direction) between the first layer  510  and the third layer  530 . 
     According to various embodiments, the nanofiber film  500  plated with a conductive material may provide a path through which noise generated in the first component (e.g., first component  401  in  FIG.  5   ) is transmitted. In the description,  FIG.  5    may be referred to together. 
     In an embodiment, the second layer  520  may electrically connect the third layer  530  and the first layer  510 . For example, as described above, in the second layer  520 , the plating solution may be relatively arranged in the vertical direction (z-axis direction) so that the noise transmitted to the first layer  510  passes through the second layer  520  and is transmitted to the third layer  530 . In addition, the nanofiber film  500  may be compressed in the vertical direction (z-axis direction) in the assembly process, and accordingly, the second layer  520  comes into close contact with the first layer  510  and/or the third layer  530  so that the conductivity between the first layer  510  and the third layer  530  can be improved. 
     According to various embodiments, the first layer  510  and/or the third layer  530  may provide a path for noise to be transmitted in the horizontal direction (x-axis direction). In an embodiment (referring to  FIG.  5    together), only part of the plurality of layers  510 ,  520 , and  530  may be formed in a partial region of the nanofiber film  500 , for example, the region of the nanofiber film  500  corresponding to the opening  421 . For example, only the first layer  510  may be formed in a partial region of the nanofiber film  500  corresponding to the opening  421 . The first layer  510  may be in contact with the first component  401  directly or via the filling member  499 , and the electromagnetic wave transmitted to the first layer  510  may be diffused in the horizontal direction (x-axis direction). As described above, the electromagnetic wave may be transmitted from the first layer  510  to the third layer  530  via the second layer  520 , and may be diffused via the shield can  420  in contact with the third layer  530 .

In an embodiment, the second layer  1120  may be plated to have better electrical conductivity in the vertical direction (z-axis direction) as compared with the first layer  1110  and/or the third layer  1130 . In another example, the first conductive material  1199   a  and/or the third conductive material  1199   c  may be arranged on the first layer  1110  and/or the third layer  1130  so as to spread in the horizontal direction (x-axis or y-axis direction). The second conductive material  1199   b  may be arranged on the second layer  1120  in the vertical direction (z-axis direction).
