PROBLEM TO BE SOLVED: To provide a lighting apparatus which looks like uniformly lighting as a whole. SOLUTION: The lighting apparatus A comprises an apparatus main unit 1 having an opening 1a, two straight tube fluorescent lamps 2a, 2b arranged in parallel along the opening 1a in the apparatus unit 1, and a louver 3 fitted at the opening 1a of the apparatus main unit 1. The louver 3 comprises first reflecting faces 3a arranged on the opposite side of the straight tube fluorescent lamps 2b, 2a that adjoin the straight tube fluorescent lamps 2a, 2b and reflect the light from the straight tube fluorescent lamps 2a, 2b frontward, and second reflecting faces 3b arranged between the straight tube fluorescent lamps 2a, 2b and reflect the light from the straight tube fluorescent lamps 2a, 2b frontward respectively. A plurality of reflecting faces of the first and second reflecting faces 3a, 3b can be visible from a person in the lighting range, and the reflecting angles of the lamp light by these plural reflecting faces are different, and diffusivity of the plural reflecting faces are made different so that the variations in brightness of these plural reflecting faces becomes small.
