PROBLEM TO BE SOLVED: To obtain manufacturing of a high quality optical fiber bundle having a high filling factor, through a simple structure simply and easily. SOLUTION: A mouthpiece 11 tacked at the end of an optical fiber bundle 10 is positioned/held by a mouthpiece receiving member 12, through which the mouthpiece is inserted into a collect chuck 13, and the end face of the optical fiber bundle 10 with the mouthpiece 11 tacked is irradiated with a luminous flux from a lamp 16 emitted to fuse. Simultaneously, the collect chuck 13 is clamped and driven through an air chuck mechanism 14 to carry out a fusion reducing process, forming a fused part 102 in the optical fiber bundle 10.
