An illuminating apparatus (24) is provided with a plurality of spot light sources (25) that emit illuminating light (L), and a light guide member (26) for guiding the illuminating light (L) to a member (23) to be illuminated. The light guide member (26) is provided with a light incoming surface (26a) for collecting the illuminating light (L) emitted from the spot light sources (25), and a reflecting surface (26b), which is composed of curved surfaces arranged at areas corresponding to the spot light sources (25), respectively, for further collecting the illuminating light (L) entered from the light incoming surface (26a) and reflecting it.The light incoming surface (26a) of the light guide member (26) is a cylindrical surface. The reflecting surface (26b) of the light guide member (26) is a conical surface. The light guide member (26) has a second reflecting surface (26c) for further reflecting the illuminating light (L) reflected by the reflecting surface (26b). |
