摘要：
In a method of producing an optical fiber coupler, in which glass portions of a plurality of optical fibers are heated so as to be fusion bonded to each other and then, are heated so as to be stretched, the improvement comprising: a gas burner which acts as a heat source and has a plurality of gas nozzles arranged in an axial direction of the optical fibers so as to be fixed in position during heating of the glass portions.
