Abstract
A combiner, that optically combines input fibers that propagate pumping light launched from pumping light sources and a relay fiber connected to an amplification fiber, includes: a bundle portion where the input fibers are bundled together; and a melting portion where the input fibers are melted and integrated together. In an interface between the relay fiber and the melting portion, the input fibers are fused together without a gap between the input fibers.
