An optical fiber array having an optical coupling end where another optical path is coupled to it. On this optical coupling end, ends of plural optical fibers are arranged. This optical fiber array comprises a lower plate (3a) where a plurality of V grooves are formed to position the optical fibers exposed at the end of the core, and an upper plate (3b) which presses the optical fibers (1) arranged in the grooves (4) in the lower plate (3b) against the V grooves (4). The boundary parts of the cores (7) and optical fibers (1) are fixed by a heat-resistant bonding agent (10) between the upper and lower plates (3a and 3b). Further, the optical fibers (1) from this boundary parts are airtightly fixed by solder (6). In this way, it is possible to implement a high hermetic seal having a sufficient airtightness. <IMAGE> |
