To allow a light source to be placed without spatial restriction and realize light emission using light emitted by the light source.SOLUTION: A vehicle window member (100) comprises a first optical singular part (103-1) and a second optical singular part (103-2) which, when light emitted by a light source (500) is incident through a light incident end face (101) and guided along a first main surface (104-1) and a second main surface (104-2), change the direction of the guided light to exit through the first main surface (104-1) and/or the second main surface (104-2) to the outside thereof.SELECTED DRAWING: Figure 2
【課題】空間的な制約を受けることなく光源を設置し、当該光源から出射される光を用いた発光を実現する。【解決手段】光源(500)の発する光が入光端面(101)を通して入射され、入射された光を第1主面(104−1)及び第2主面(104−2)に沿って導光し、導光された光を第1主面(104−1)及び第2主面(104−2)のうち少なくとも一方からその外側へ出射させるように、光の導光方向を変化させる第1光学的特異部(103−1)及び第2光学的特異部(103−2)と、を備える車両窓部材(100)である。【選択図】図2
