摘要： PROBLEM TO BE SOLVED: To provide a reliable mechanical splice.
SOLUTION: Opposed optical fibers 2a and 2b are butted and connected in the state where coated optical fiber 2aa and 2ba at the tip part are bent. Because each coated optical fiber 2aa and 2ba comes into contact with either a V-grooved substrate 4 or a presser foot substrate 5, bending does not advance from an initial state, and optical loss is not increased. Thereby, the breaking of wire of the optical fibers 2a and 2b is prevented, and the initial state is maintained with high reliability.
