Abstract
The optical fiber fusion splice structure has a fusion splice portion at which the bare fibers exposed from the coverings are connected to each other by fusion splicing, a fiber accommodation portion having a fiber accommodation groove formed along an axis of the optical fibers, and fixation resins for fixing a portion of the coverings on both sides of the fusion splice portion within the fiber accommodation groove. The fiber accommodation groove receives a portion of the optical fibers including the fusion splice portion. The fixation resins are formed so as to fill the fiber accommodation groove in a depth direction. A pipe member that allows an infrared ray to pass therethrough is attached around the fiber accommodation portion so as to surround a space between the fixation resins on both sides of the fusion splice portion within the fiber accommodation groove.
