PURPOSE:To fix a bare optical fiber in the internal hole of a connector speedily by interposing a hot-melt adhesive in the gap of the bare optical fiber terminal inserted into the internal hole of the connector, and heating it from the outer periphery of the connector and melting the hot-melt adhesive. CONSTITUTION:The coating 1A of the coated optical fiber 1 at a terminal is removed by specific length to expose the bare optical fiber 1B and a pipe 4 made of the hot-melt adhesive is fitted around the exposed bare optical fiber 1B. Then, the terminal of the bare optical fiber 1 sheathed with the pipe 4 is inserted into the internal hole 2A of the connector 2 and heated by a heater 5 from outside the connector 2 to heat and melt the pipe 4 made of the hot-melt adhesive in the internal hole 2A, thereby fixing the coated optical fiber 1 and connector 2. The pipe 4 hardens immediately by being cooled after being molten, so the end surface of the optical fiber 1 to which the connector 2 is fixed is polished immediately.
