PROBLEM TO BE SOLVED: To provide a folding type mobile telephone set which can confirm display contents of an LCD, even in a folded state without increasing the number of components, a mass, or a power consumption by a large amount. SOLUTION: In an earphone part A, the front side display window which exposes one surface of an LCD and the back side display window which exposes an opposite surface are opened. A reflection lid 23, formed with optical reflection surfaces on both surfaces, is fitted to the earphone part A so as to make it turn to a position covering a front side display window 17 and a position covering a back side display window 18. A reflection lid 23 is arranged in the position covering the back side display window 18, to confirm a display of the LCD from a front side, and the reflection window 23 is arranged in the position covering the front side display window 17, to confirm the display of the LCD from a back side.
