PROBLEM TO BE SOLVED: To provide a blind member and a window member capable of shielding sunlight at a high angle while ensuring the transparency of a window.SOLUTION: A sheet-like blind member has two or more shielding/transmitting layers disposed facing to each other being interposed by a predetermined distance. Each of the shielding/transmitting layers has plural light shielding strips 4a and 4b and plural transmission strips 5a and 5b which are disposed alternately in a height direction. The two or more shielding/transmitting layers are formed with identical phase in the height direction. Defining the width of the light shielding strip as Wb, the predetermined distance as T and an angle of a light beam entering an upper part of the window at a critical angle forming with a normal direction of the window inside the blind member as α, Wb<T×tanα is satisfied. |
