PROBLEM TO BE SOLVED: To provide a vertical louver for improving visibility through a window opening while taking in reflected light through the window opening.SOLUTION: A vertical louver 1 includes an outer louver board 20, and an inner louver board 30 arranged closer to a building B than the outer louver board 20. The outer louver board 20 and the inner louver board 30 are arranged so as to be offset at predetermined intervals in a direction orthogonal to inner/outer direction of the building B. A side of the outer louver board 20 facing the inner louver board 30 is provided with a first concave surface 23. A side of the inner louver board 30 facing the outer louver board 20 is provided with a second concave surface 33. The outer louver board 20 and the inner louver board 30 are set at different arrangement angles. |
