PROBLEM TO BE SOLVED: To improve working efficiency during assembly work.SOLUTION: There are provided a plurality of base plates 11, 12, 13, 14; a flexible printed wiring board 20 having a plurality of areas including at least a first area 21, second area 22 and third area 23 and having each of the areas being fixed to each of the plurality of base plates, a light source 30 arranged in the first area and an electric power supply part 40 arranged in the second area to supply electric power to the light source. Since the flexible printed wiring board having the first area, second area, third area and fourth area is bent between each of the areas, it is not necessary to perform a bending processing of each of the base bodies formed by metallic material, the working steps can be decreased and a working efficiency at the time of assembling work can be improved. |
