摘要： An optical transmission element according to an embodiment comprises a fiber and a covering layer. The fiber includes a core made of glass and a cladding made of glass covering an outer periphery of the core. The covering layer covers an outer periphery of the cladding and includes a plurality of alkyl groups which are not fluorine-substituted wherein each of the alkyl groups is bonded to the cladding via a siloxane bond and wherein the alkyl groups are represented by CH3(CH2)n— wherein m is an integer of 7 or more.

摘要： An object of the present invention is to provide an optical fiber bundle having high adhesive strength at an end, and an endoscope using the optical fiber bundle. Another object of the present invention is to provide a method of producing the optical fiber bundle having high adhesive strength at an end. An embodiment of the present invention provides an optical fiber bundle including a bundle of optical transmission elements, each of which includes a fiber including a core made of a first glass and a cladding made of a second glass and covering an outer periphery of the core, and a covering layer covering the outer periphery of the cladding. The covering layer includes an alkyl group having 1 to 7 carbon atoms and not being fluorine-substituted. The alkyl group is bonded to the cladding via a siloxane bond.
