A number plate including luminous characters is usually mounted below head lamps of a vehicle. As essential components, this number plate includes a front plate having a plurality of character portions punched therefrom a plurality of characters each molded of a transparent or translucent synthetic resin and adhesively fitted into the character portions, a plurality of electroluminescent plates disposed on the rear surface side of the front plate so as to illuminate the character portions, a DC/AC inverter disposed on the bottom side of a case of the number plate and electrically connected to the electroluminescent plate and a power source, a plurality of base boards each fitted to an electroluminescent plate and having the substantially same area as that of each character portion, and a support portion for supporting the base boards thereon. When the base boards are fitted to the support portion, the latter serves as two electrodes for the electroluminescent plates, whereby the support portion is electrically connected to the electroluminescent plates via the foregoing two electrodes.
