Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a light guide device which can be made thin.SOLUTION: A light guide device 3 comprises a light transmission body 5 and a light transmission body 6. The light transmission body 6 comprises a main inclined part 9 and a sub inclined part 10. The main inclined part 9 has an inclined surface 15 and an inclined surface 16 formed. The main inclined part 9 allows light, reflected by the inclined surface 15 and inclined surface 16, to impinge on the light transmission body 5. The sub inclined part 10 reflects incident light by an inclined surface 20 to let the light impinge on the light transmission body 5. The inclined surface 20 comes closer to a surface 7 as being away from the main inclined part 9.SELECTED DRAWING: Figure 2 【課題】薄型化が可能な導光装置を提供する。【解決手段】導光装置３は、透光体５及び透光体６を備える。透光体６は、主傾斜部９及び副傾斜部１０を備える。主傾斜部９に、傾斜面１５及び傾斜面１６が形成される。主傾斜部９は、傾斜面１５及び傾斜面１６で反射した光を透光体５に入射させる。副傾斜部１０は、入射された光を傾斜面２０で反射させ、透光体５に入射させる。傾斜面２０は、主傾斜部９から離れるに従って表面７に近づく。【選択図】図２
