Abstract

PURPOSE:To provide a filling method of an adhesive into a ferrule which it can be carried out in a short time and the intrusion of air bubbles is prevented very easily. CONSTITUTION:The ferrule 1 is covered on a needle 7 which is faced to the upper side from a core hole 2 and a high viscous adhesive 4 is injected from a tip of the needle 7. The adhesive 4 is filled from the inner part of the core hole 2 but it does not enter a naked optical fiber hole 3, because it is high viscous. Since the ferrule 1 is light in weight, it is pushed up with the adhesive 4 which is filled into the core hole 2. When the core hole 2 is perfectly filled with the adhesive, the adhesive 4 filled in the core hole 2 is sucked by suction force from the naked optical fiber hole 3 and the naked optical fiber hole is filled.
