Abstract: A daylighting slat (40) includes a daylighting plate (40) extending in one direction. The daylighting plate (40) includes: a transparent base material (41) having a curved or angled shape in a cross-section taken perpendicular to a lengthwise direction of the daylighting plate (40); a plurality of transparent daylighting sections (42) at least in a first region (41Aa) of a first face (41A) of the base material (41); and gap portions between the daylighting sections (42), wherein each of the daylighting sections (42) has a side face in contact with one of the gap portions, a part of the side face serving as a reflection face where light incident to that daylighting section (42) is reflected.
