<p><P>PROBLEM TO BE SOLVED: To provide a communication device capable of obtaining wide-band and high-gain antenna characteristics without disposing a feeder inside a connection part. <P>SOLUTION: A mobile telephone 1 includes a circuit board 70 disposed at an operation unit-side casing 2, a circuit board 80 disposed at a display unit-side casing 3, a circuit portion formed on the circuit board 70 and having a ground pattern and a contact point 104, a reference potential pattern layer 75 disposed at the operation unit-side casing 2 and electrically connected to the ground pattern, a reference potential pattern layer 86 disposed at the display unit-side casing 3, and an FPC unit 101 for electrically connecting the circuit board 70 with the circuit board 80. The FPC unit 101 has a signal line 210 for transmitting a predetermined signal and a shield layer 240 for electrically shielding the signal line 210. The shielding layer 240 is electrically connected to the contact point 104 in the operation unit-side casing 2 and is thus electrically connected to the reference potential pattern layer 86 in the display unit-side casing 3. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
