Portions of lateral surfaces of the daylighting parts in contact with the gaps serve as reflection surfaces that reflect light incident on the daylighting parts. The daylighting parts have characteristics of dispersing and emitting light reflected on the reflection surfaces in directions crossing a direction in which the daylighting parts extend. The plurality of daylighting parts extend at an angle of -45 to +45° with respect to an end edge of the base material along the vertical direction.
