    摘要： An optical fiber splicing tool of the invention include: an optical fiber splicing unit (10) that includes: a mechanical splice holder that holds a mechanical splice (30); an optical fiber grasper (70) that grasps a first optical fiber at one end side of the mechanical splice (30); and a guide target that is slidable along a guide provided at a connecting jig (110) that fixes a second optical fiber to be butt-jointed to the first optical fiber; and a connecting jig (110) that includes: a guide that guides the optical fiber splicing unit (10); and an optical fiber fixer (90) that fixes the second optical fiber. The optical fiber splicing unit (10) provides a first flexure width (L1) between one end side of the mechanical splice (30) and the optical fiber grasper (70), and a second flexure width (L2) shorter than the first flexure width (L1) is ensured between the other end side of the mechanical splice (30) and the optical fiber fixer (90) when butt-jointing is carried out.
