Abstract
A light guide is configured to allow at least a portion of light incident on a light-incident surface to be emitted through a peripheral surface. The light guide includes a light guide portion extending in a lengthwise direction of the light guide and formed of a first material and a luminous portion extending in the lengthwise direction of the light guide along the light guide portion and formed of a second material. The second material has a haze value greater than a haze value of the first material.
