A UV shielding material or UV absorbing material is incorporated into the tubular clad 3. The light transmission tube is produced by using a multicolor extruder, simultaneously introducing the core material, the clad material and the reflection materials contg. white pigments or scattering materials into the respective mouthpiece parts of the extruder and respectively simultaneously extruding the core material to a columnar shape, the reflection materials to belt forms on the outer peripheral surface of the columnar core material and the clad material to a tubular form covering the core material and the reflection material.
