PROBLEM TO BE SOLVED: To approximately uniformly emit light from a plurality of branch portions to improve appearance.SOLUTION: A light guide member includes: one incident surface 50; four emission surfaces 51; and a light guide portion 52. The light guide portion 52 is composed of a stem provided with the incident surface 50, and four branch portions 54 respectively provided with the emission surfaces 51. A guide portion for guiding the light in the stem 53 while approximately uniformly branching the same into the plurality of branch portions 54, is disposed between the stem 53 and the branch portions 54. As a result, four branch portions 54 can approximately uniformly emit the light. 【課題】見栄え上、複数本の枝部がほぼ均等に発光することが重要である。【解決手段】この発明は、１個の入射面５０と、４個の出射面５１と、導光部５２と、を備える。導光部５２は、入射面５０が設けられている幹部５３と、出射面５１がそれぞれ設けられている４本の枝部５４と、から構成されている。幹部５３と枝部５４との間には、幹部５３中の光を複数本の枝部５４中にほぼ均等に分岐して導くガイド部が設けられている。この結果、この発明は、４本の枝部５４がほぼ均等に発光することができる。【選択図】 図２
