Abstract

PURPOSE:To achieve the miniaturization and simplification and enable the increase in water pressure resistance strength by providing the metal discs having plural optical fibers through-holes in a lead-in hole, inserting optical fibers into these through-holes and fixing these by means of adhesive agents. CONSTITUTION:Metal discs 6-1, 6-2 are fixed in the lead-in hole 5 of the optical fiber lead-in part, and optical fibers 3-1, 3-2 are inserted into the optical fiber through-holes 7-1-7-4 provided to the metal discs 6-1, 6-2. These optical fibers 3-1, 3-2 are secured by means of adhesive agents 8-1, 8-3.... Since such construction enables the simultaenous leading-in of a multiplicity of optical fibers, it makes it possible to achieve the miniaturization and simplification of the lead-in part. In addition, the construction comprising laminating the plural metal discs 6-1, 6-2 in the adhesive agents 8-1, 8-2, 8-3... enables the achievement of the considerable increase in water pressure resistance strength.
