PROBLEM TO BE SOLVED: To provide a plate-shaped vehicular light guide member with a uniform light-emitting surface.SOLUTION: A plate-shaped light guide member 5 of the present invention includes a plane 50 of incidence, an emission surface 51, and a minute reflecting surface 52. The minute reflecting surface 52 comprises a profile curve for reflecting light (incident light L2), which passes through a virtual focus F, in parallel with or almost in parallel with the side of the emission surface 51. Consequently, the plate-shaped light guide member 5 of the present invention can obtain a uniform light-emitting surface.SELECTED DRAWING: Figure 1 |
