As is apparent from the above description, the joint terminal of the present invention is provided with a straightening wall projecting so as to be smaller in diameter than three sides of the left and right side portions of the barrel and the tip end surface of the bottom portion. For this reason, the branch wire is corrected so that the tip of the core wire contacts the correction wall and faces inward. Therefore, it is possible to prevent the tip of the core wire from jumping out, and to prevent the tape from being cut by the projected core wire. Further, it is possible to prevent the core wire from projecting and exposing to the outer surface of the tape when the tape is loosened.
