PROBLEM TO BE SOLVED: To improve traffic safety by filling a transmissible synthetic resin forming a base board in a metallic case and arranging a lamp and also arranging an irregular reflection part at least at one of the front and rear faces of the base to constitute the mainbody of a traffic sign board and further, sticking a transmissible sheet expressing the contents of the sign on the front face of the body. SOLUTION: A traffic sign board 1 is made of a metallic material such as aluminum alloy, and a plurality of lamps 3 such as light-emitting diode lamps are arranged at every appropriate distance on the whole periphery of the circumference in the inside of a case body 2 having an opened face at the front side. And a transmissible synthetic resin 4 forming a base board 11 is charged in the inside of the case body 2. and the lamps 3 are embedded in the synthetic resin 4. An irregular reflection member 8 are arranged at both front and rear faces of the base board 11 made of synthetic resin 4 and the main body 5 is constituted of the case body 2, the lamps 3, the synthetic resin 4, and the irregular reflection member 8. A transmissible sheet 7 expressing the contents of the sign is stuck on the synthetic resin 4 face 4 forming the front face of the main body 5. |
