To cause a light-emitting component for a vehicle including a curved plate-shaped transmission body to uniformly emit light.SOLUTION: A light-emitting ornament installed in a vehicle includes as a light-emitting region: a light source unit which has a lamp being a point-like light source and a planar light guide body having an emission surface emitting light from the lamp and emits the light toward a front side of the light-emitting region; and a curved plate-shaped ornament which makes the light emitted from the light source unit transmit therethrough at the front position of the light source unit. The ornament includes a portion having a different interval from the light guide body. The light-emitting ornament further includes a surface luminance adjustment unit which adjusts luminance of an outer surface of the ornament according to magnitude of an interval between the ornament and the light guide body.SELECTED DRAWING: Figure 7

    【課題】曲板形状の透過体を備える車両用発光部品を均一に発光させる。【解決手段】車両に設置される発光オーナメントは、点状光源であるランプとランプからの光を出射する出射面を備えた平板状の導光体とを有して発光領域の前方に向けて光を照射する光源ユニットと、光源ユニットの前方位置にて光源ユニットから出射された光を透過させる曲板状のオーナメントと、を発光領域として備える。オーナメントは、導光体との間隔が異なる部位を有する。そして、発光オーナメントは、オーナメントと導光体との間隔の大きさに応じてオーナメントの外表面の輝度を調整する表面輝度調整部を更に有する。【選択図】図7
