摘要：
The portable telephone has an optical signal transmission section 100 for performing signal transmission between a first casing 101 and a second casing 102 by optical signals. A need for any complex electromagnetic shield structure can be eliminated. There is no occurrence of electromagnetic-wave noise from an optical signal transmission section 100. Thus, electromagnetic-wave noise of the whole portable telephone can be extremely reduced.
