PROBLEM TO BE SOLVED: To provide a device and a method of manufacturing optical fiber couplers in a fashion capable of holding a uniform shape. SOLUTION: The manufacturing device 2 is constituted such that, in the first and second coated optical fiber tapes 32, 33 clamped by setting clamps 12-15, the optical fibers 32a, 33a with the coating removed over a prescribed section of these tapes inside the setting clamps are clamped by a pair of drawing clamps; that the bare fibers 32b, 33b with the coating removed over a prescribed section inside the pair of drawing clamps 16, 17 are clamped by a pair of fusion clamps 18, 19; that the bare fibers are heated and fused in close contact with each other, the fused part is drawn by the drawing clamps to form plural optical fiber couplers; and that each setting clamp is equipped with an air cylinder 34 for releasing the setting clamps simultaneously. |
