Claims

[Scope of utility model registration request]

It consists of a hollow light guide tube and a closing member for closing the hollow portion on the light receiving end side of the light guide tube, and the closing member has a refractive index equal to or lower than the refractive index of the light guide tube. 1. A light guide tube, characterized in that the end portion of the closing member within the light guide tube is formed with a flat surface, a convex surface, or a concave surface.
