LIGHT GUIDE MEMBER AND METHOD FOR PRODUCING LIGHT GUIDE MEMBER

摘要

A light guide member includes a transparent part and a reflective part. The transparent part has an elongated shape. The transparent part includes a light entrance part to be struck by light and a light exit part for allowing light to emerge outside. The light entrance part is an end surface of the transparent part in a longitudinal direction. The light exit part is a surface extending along the longitudinal direction of the transparent part. The reflective part is provided along an opposite surface of the transparent part from the light entrance part. The reflective part is for reflecting light entering the light guide member through the light entrance part toward the light exit part. The transparent part and the reflective part are formed by double extrusion.
