ELECTRONIC DEVICE

To provide an electronic device capable of suppressing a decrease in antenna performance, and to provide a casing member used for a casing of the electronic device.SOLUTION: An electronic device includes: an outer wall; a first casing member having an antenna element for forming one portion of the outer wall; and a second casing member relatively rotatably connected to the first casing member between a first posture for covering the surface of the first casing member and a second posture for exposing the surface of the first casing member. A frame that is formed from a conductive material and is disposed so as to cover the antenna element from above in the first posture is provided in an outer peripheral part of the second casing member. The first casing member further covers the entire surface of the antenna element, and includes an electric wave transmitting member interposed between the antenna element and the frame in the first posture.SELECTED DRAWING: Figure 4 【課題】アンテナ性能の低下を抑制することができる電子機器及び該電子機器の筐体に用いる筐体部材を提供する。【解決手段】電子機器は、外壁と、前記外壁の一部を形成するアンテナ素子とを有する第１筐体部材と、前記第１筐体部材の表面を覆う第１姿勢と、前記第１筐体部材の表面を露呈させる第２姿勢との間で、前記第１筐体部材に対して相対的に回動可能に連結された第２筐体部材と、を備える。第２筐体部材の外周縁部には、導電性材料で形成され、前記第１姿勢時に前記アンテナ素子を上から覆うように配置されるフレームが設けられる。第１筐体部材は、さらに、前記アンテナ素子の表面全体を覆い、前記第１姿勢時に前記アンテナ素子と前記フレームとの間に介在する電波透過性部材を有する。【選択図】図４
