LIGHT TRANSMISSION BODY

摘要

Provided is a light transmission body which has a good balance among excellent durability, wear resistance, lubricity and excellent adhesiveness. A light transmission body according to one embodiment of the present invention comprises a fiber strand and a covering layer. The fiber strand is configured of: a core that is formed of glass; and a cladding that covers the outer circumferential surface of the core and is formed of glass. The covering layer is composed of a plurality of alkyl groups which cover the outer circumferential surface of the cladding and are not substituted by fluorine, and each alkyl group is bonded to the cladding via a siloxane bond.
