PROBLEM TO BE SOLVED: To provide a light guide member capable of preventing increase of manufacturing cost and enhancing reflection efficiency of a reflection part, and to provide a method for manufacturing the light guide member.SOLUTION: A rod-like light guide member 1 is provided, and comprises a transparent part 4 which has an end face in the lengthwise direction which serves as a light-incident part 42 into which light from a light source 20 comes, and one face along the lengthwise direction which serves as a light-emission part 43 emitting light. The light guide member 1 also comprises a reflection part 5 provided in the transparent part 4 along a face facing the light-emission part 43 and reflecting light incoming from the light-incident part 42 to the light-emission part 43. The transparent part 4 and the reflection part 5 are formed through two-color extrusion molding of synthetic resin materials each having a different refraction index. |
