As illustrated in FIG. 5A, when the side member 200 is viewed from a side, the polymer part 230 may include a first portion 231 adjacent to an edge of the first metal part 210 and a second portion 232 visible through the opening 250. For example, as illustrated in FIG. 5B, when the side member 200 is viewed from above, the first portion 231 of the polymer part 230 may be coupled to the surface of the side member 200.
In an embodiment, the first portion 231 of the polymer part 230 may face the first cover 120 or the second cover 180. For example, the first portion 231 of the polymer part 230 may include an area on which a front plate (e.g., the first cover 120 of FIG. 3) or a back plate (e.g., the second cover 180 of FIG. 3) is seated. For example, the first portion 231 of the polymer part 230 may include an area on which a display (e.g., the display 130 of FIG. 3) is seated.
In an embodiment, an adhesive layer 260 may include the first adhesive layer 261 formed between the first metal part 210 and the polymer part 230 and the second adhesive layer 262 formed between the second metal part 220 and the polymer part 230. In an embodiment, the adhesive layer 260 may contain an organic material (e.g., carbon).
