摘要： A lighting apparatus (12) has a plurality of tubular light sources (17) arranged in parallel and a light reflective member (40) arranged at the opposite side of the light emission side of the tubular light sources. Arrangement of the tubular light sources is configured to have narrow interval sections (17A) with relatively narrow-spaced arrangement intervals and wide interval sections (17B) with relatively wide-spaced arrangement intervals. On the light reflective member, openings (50) are formed such that an aperture ratio equivalent to a formation ratio of the openings (50) to a whole area of the light reflective member (40) becomes greater in the narrow interval sections (17A) than in the wide interval sections (17B). The lighting apparatus is characterized by such a configuration.
