Abstract: A portion of one conductor is bent to form a facing portion where two regions face each other, the facing portion and another conductor are inserted into a ring-shaped caulking member, and crimping is effected. This obviates the need for cutting a conductor in the work of coupling the conductor with a plurality of branch lines and the need for preliminarily threading the conductor through ring-shaped caulking members. Thus, it is feasible to improve reliability of electrical connection and to add a new branch line readily.
