Abstract

An excellent optical fiber built-in type composite insulator including at least two insulator bodies each having a penetration bore, at least one optical fiber inserted in the penetration bores, and sealing structures for the penetration bores of the insulator bodies and for a joining layer of opposing end surfaces of adjacent insulator bodies, is provided, which effectively prevents leakage of inner silicone grease, bending and breakage of the optical fiber, leakage of electric current along the penetration bores, short circuited trouble, and destruction of the insulator bodies, improves joining strength of the opposing end surfaces of the insulator bodies, and maintains the joining strength for a long period, affords a change of numbers of the insulator bodies, and facilitates the production. A method of producing such composite insulator is also provided.
