Abstract: An electronic device and a housing structure thereof are provided. The electronic device includes a transparent member; a metallic housing surrounding a boundary of the transparent member, and forming a lateral outer appearance of the electronic device; and a non-metallic absorption member arranged inside the metallic housing. The non-metallic absorption member is arranged to face a side surface of the transparent member. The metallic housing comprises a protection portion arranged adjacent to the boundary of the transparent member. An interlace between the non-metallic absorption member and the protection portion, which faces the transparent member, is disposed inward relative to a first virtual extension line virtually extending along an external surface of the transparent member. An inner surface of the protection portion facing the non-metallic absorption member includes a surface inclined at a preset angle with respect to a front or rear direction of the electronic device.
