Abstract

An object is to provide a daylighting sheet which efficiently performs daylighting and in which, when the daylighting sheet is applied to a window of a building or the like, it is possible to see an outdoor side. The daylighting sheet includes a translucent base material layer; and a light deflection layer that is formed on the base material layer, and the light deflection layer includes: light transmission portions that are aligned along one surface of the base material layer so as to be able to transmit light, each of which including a groove at a portion being in a light entering side in a position where the light transmission portion is arranged in the opening portion of a building; and light deflection portions that are formed between the light transmission portions and filled with a material whose refractive index is lower than that of the light transmission portions.
