Abstract
An end face of a plastic optical fiber end is treated so as not to extrude to the core side face when the plastic optical fiber end is softened and fused. The core end face of the plastic optical fiber end is pressed intermittently on a mold that is heated to a certain temperature to soften and fuse the core end face to thereby transfer the transfer face of the mold on the core end face.
