Abstract
The portable telephone has an optical signal transmission sectionfor performing signal transmission between a first casingand a second casingby 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. Thus, electromagnetic-wave noise of the whole portable telephone can be extremely reduced.
