PURPOSE: To form lenses having a high degree of freedom in shapes with excellent productivity at the end faces of optical fibers. CONSTITUTION: A device consists of the plural optical fibers 10 arranged at prescribed intervals (pitches) and a member 2 having plural lens forming holes 21 corresponding to the pitches of the optical fibers 10. Transparent resins 31 curable by light or heat are packed into these holes 21 and thereafter, the optical fibers 10 are inserted to the prescribed extent into the holes 21 to project the resins 31 from the holes 21, by which projecting parts 32 are formed at the ends of the holes. Light or heat is applied on these projecting parts 32 to cure the resins, by which the lenses 30 are formed at the end faces of the fibers 10. |
