PURPOSE: To easily manufacture an optical distributor having a shape like an orange cut surface, by an inside pipe consisting of glass, etc. in the center part, arranging plural optical fibers so that they are made to tightly adhere onto the outside circumference of the inside pipe, and heating and melt-sticking them from the outside.

CONSTITUTION: Plural optical fibers 1 are arranged so that they are made to tightly adhere onto the outside circumference of an inside pipe 8, and its outside circumference is covered with an outside pipe 11. When they are heated and melt- stuck from the outside, an optical distributor whose section is an orange cut surface shape. When connecting with a single optical fiber, the end part is drawn out at the time of melt-sticking, its diameter is made thin, and it is connected with the end part of the optical fiber.
