<p>PROBLEM TO BE SOLVED: To provide the portable telephone of a structure capable of smoothing the deterioration of the sensitivity of communication caused by the positional relation of the base station of the portable telephone and the electromagnetic wave protection of the portable telephone. SOLUTION: A non-directional reflector 1 is turned to an opening and closing type. Then, in the state of folding the non-directional reflector 1, the non- directional reflector 1 is provided with a convex curved surface. The surface layer 2 is a material capable of reflecting/interrupting radio waves and is also provided with a mirror surface structure capable of controlling the reflection direction of the radio waves. Then, on the back side, a speaker is installed. Also, an antenna 4 is basically positioned at the center of this portable telephone.</p> |
