Abstract
A daylighting device of the present invention is provided with a planar optical member 1 and a support member. The planar optical member 1 is provided with a planar structure body which has a plurality of linear bodies 3 formed of optically transparent materials which are arrayed substantially in parallel and a plurality of binding members which are arranged in a direction which intersects with the plurality of the linear bodies 3 and which bind the plurality of the linear bodies 3 in a state of being arrayed substantially in parallel. The linear bodies 3 have reflective surfaces which reflect light which is incident to the linear body 3 along a direction which intersects with a length direction of the linear body 3 and refractive surfaces which refract the light.In at least a part of a planar structure body, the orientations of reflective surfaces of at least some of the linear bodies out of the plurality of linear bodies 3 substantially match and the orientations of the refractive surfaces of at least some of the linear bodies substantially match.
