Description

  The present invention relates to an electronic device such as a mobile phone having two or more housings that are connected to be openable and closable.

In such an electronic device, circuit boards housed in the respective housings are electrically connected by cables. The cable is likely to be mixed with noise due to the influence of static electricity that has entered from the gap between the connecting portions connecting the housings. Therefore, various techniques for shielding the cable have been proposed (for example, Patent Documents 1 to 3).
