PURPOSE: To set off the existence of a displayed object at low cost and to emphasize one part of the displayed object in a pin-point manner.

CONSTITUTION: Concerning the light emitting instrument to be used for setting off the existence of the displayed object, this instrument is provided with a light transparent cover 1 for which its lower part is opened and an uneven part 2 for scattering transmitted light to the outside is formed on its inner face, a fitting base plate 4 attachably and detachably fitted to a lower opening 3 of the light transparent cover 1 so as to close the opening, electrically insulated based plate 6 attachably and detachably held at the fitting base plate 4 and the opening part of the light transparent cover 1, a light emitting diode 13 connected between terminals installed on the side of the uneven part 2 on the electrically insulating substrate 6, a battery 7 attachably and detachably inserted between a fixed electrode 8 installed on the electrically insulating base plate 6 on the side of the fitting base plate 4 and a torsional electrode 9 so as to supply power for turning-on to the light emitting diode 13, and a fixed member installed on the rear of the fitting base plate 4 and fixed to the background base material of the displayed object.
