Claims

[Scope of utility model registration request]

A light guide made of translucent plastic or glass, which forms an optical path for guiding output light from the optical semiconductor element or input light to the optical semiconductor element, is housed in a light-shielding case body, and the protrusion of the case body is A light guide device characterized in that only a part of the outer periphery of the light guide body is tightly attached and held at a portion of the light guide body.
