Abstract

A reflection structure configured to be disposed on a light guide body that guides a light beam incident from a light source and causes the light beam to exit from a light emitting area set in a light exit surface, having a reflection surface that reflects the light beam emitted from the light source toward the light emitting area. When the reflection structure is viewed from a direction perpendicular to the light exit surface, a pointed end is arranged in a direction orthogonal to a traveling direction of the reflected light beam, and an angle formed between the traveling direction of the reflected light beam and a normal direction of an end edge of the reflection surface connected to the pointed end is less than or equal to −38.327x2+152.3x−94.014, wherein x is a refractive index of the light guide body.
