Abstract
A lens frame, made from metal, retaining a light-emitting lens and a light-receiving lens is retained between a second mold and a third mold both of which are made from light-shielding resins. The lens frame has an asperity structure on its front and back surfaces. This greatly enhances adhesiveness between the light-emitting lens and the lens frame and adhesiveness between the light-receiving lens and the lens frame, thus preventing sliding of the light-emitting lens and the light-receiving lens over the lens frame.
