To provide a vehicular window unit having high light utilization efficiency.SOLUTION: A vehicular window unit 100 comprises a light source part 410, a light guide part 200, and a black part 300. The light guide part 200 is formed into a plate-shape, and comprises an introduction part 201 including an incident surface on which light emitted from the light source 410 is incident, a flat plate part 202 through which the light introduced into the introduction part 201 is passed, a curved part 203 for changing a traveling direction of the light passed through the flat plate part 202, and an emitting part 204 for emitting the light passed through the curved part 203. The introduction part 201 introduces the light emitted from a light source, in a direction along a planar direction of the flat plate part 202 toward the flat plate part 202. The black part 300 is provided on a planar part 202a located on an interior side of a vehicle out of the flat plate part 202.SELECTED DRAWING: Figure 3

    【課題】光の利用効率が高い車両用窓ユニットを提供する。【解決手段】車両用窓ユニット100において、光源部410と、導光部200と、黒色部300と、を備える。導光部200は、板状に形成されており、光源部410から出射された光を入射させる入射面を含む導入部201と、導入部201に導入された光を通過させる平板部202と、平板部202を通過させた光の進行方向を変更させる湾曲部203と、湾曲部203を通過した光を出射させる出射部204と、を有する。導入部201は、光源から出射された光を、平板部202に向けて平板部202の平面方向に沿う方向に導入させる。黒色部300は、平板部202のうち車両の車内側に位置する平面部202aに設けられている。【選択図】図3
