PROBLEM TO BE SOLVED: To provide a traffic sign which is inexpensive and has good visibility. SOLUTION: The traffic sign 10 has a character 'STOP' and is formed by aminating and arranging a sheet 11 having this character, a plate 12 made of a transparent synthetic resin adhered with the sheet 11, a light transmission plate 13 made of a transparent synthetic resin and a reflection plate 14 in this order. A light transmission tube 1 is embedded and integrated in the peripheral edge of the light transmission plate 13. Light is introduced from a light source unit 15 into the light transmission tube 1 and this light is introduced into the light transmission plate 13 from the side peripheral surface of the light transmission tube 1 and transmits the plate 12 and the sheet 1. This light transmission tube is produced by a three-color extrusion molding method. |
