PROBLEM TO BE SOLVED: To provide a lens connecting rod tunnel which can shorten the working process in a simple configuration while reducing the manufacturing cost that much, and suppress the attenuation of the intensity of the light emitted from light source and forgoes the adjustment of the relative position of the lens and the rod tunnel while shortening the manufacturing period that much. SOLUTION: The lens connecting rod tunnel has a rod tunnel 3 and a lens 4. The rod tunnel 3 is a rectangular parallelepiped. The lens 4 has a curved surface 41 on one side and a flat surface 42 on the other side. The output surface 32 of the rod tunnel 3 and the flat surface 42 of the lens 4 are firmly adhered together by using a UV adhesive which is hardened by irradiation with UV light.
