PROBLEM TO BE SOLVED: To allow a light emitting element to emit light with sufficient brightness without changing the effective length of an antenna. SOLUTION: This device is provided with one loop circuit including a light emitting element 14 and a rectifier element 13 in a loop, another loop circuit connected with one part of this one loop circuit, and holding body 11 for holding this one loop circuit and the other loop circuit, and this one loop circuit and the other loop circuit are formed of a conductive thin film 12. When the holding body 11 is allowed to approach an antenna 10 radiating a radio wave, high frequency currents are induced to the loop circuit on the holding circuit 11, and converted into pulse currents by the rectifier element 13, and added to the light emitting element 14 so that the light emitting element 14 can emit light with brightness corresponding to the size of the induced currents. Thus, the sufficient brightness can be easily obtained by increasing the induced currents by properly adjusting the size of the loop circuit according to use frequencies. Also, the loop circuit and the antenna 10 are not brought into contact with each other so that the effective length of the antenna can not be largely affected.
