Description

  The present invention relates to an electronic device.

  In recent portable electronic devices, those including a first housing and a second housing that can be superposed on each other are becoming mainstream. In such a portable electronic device, the housings are connected by connection wiring such as a flexible wiring board (FPC), and transmission / reception of electrical signals is realized between the housings.

  In such a portable electronic device, since the connection wiring is inserted into the housing in order to connect to the wiring board inside each housing, the connection wiring insertion port is provided in the housing. In order to prevent water from entering the housing from the insertion port, a cap for closing the insertion port of the housing is provided on the outer periphery of the connection wiring, and a packing is provided on the outer periphery of the cap to seal the insertion port in a watertight manner. Some have a structure (see, for example, Patent Document 1). The cap can be formed integrally with the outer periphery of the connection wiring by, for example, insert molding in which a connection wiring is loaded in a mold and then resin is injected and the connection wiring is wrapped with a molten resin and solidified. .
