The pair of electrodes 7 are disposed so as to oppose each other on a fusion part where tips of the optical fibers are butted and fused together, and a hollow core fiber 21 is positioned between the electrodes 7. By applying a prescribed voltage across the electrodes 7, an arc 23 is generated in a straight line connecting the tips of the pair of electrodes 7. At such time, the axial center connecting the tips of the pair of electrodes 7 is offset relative to the axial center of the hollow core fiber 21 held by an optical fiber holding part. In a state where the arc 23 is formed by applying a voltage across the electrodes 7, a control unit can rotate a pair of holder mounting parts 11 about the axis of the hollow core fiber 21 and in the same direction at a predetermined speed.
