不向きであった。However, in the above-described conventional electric wire joint method, the conductors 2b of the joint portions J of the plurality of electric wires 2 are joined together by thermocompression bonding. As described above, when performing the joint operation, the tip of the conductor 2b of each electric wire 2 is likely to be displaced or the like, and it is difficult to maintain a high quality by that much. In addition, as shown in FIG. 11, when performing joint work, it is difficult to set each of the electric wires 2 unless a positioning component 7 or the like is used to simultaneously align the ends of the conductors 2b of the plurality of electric wires 2. However, it has been difficult to maintain the quality at a constant level due to the displacement. Further, FIG.
As shown in (a), (b), and (c), when waterproofing is performed as the post-joining process, there is a possibility that water may enter inside in the state of FIG. As shown in FIG. 12), a flat state is desirable, but it is difficult to form the insulator 3 flat, and as shown in FIG. Furthermore, since the conductors 2b of the joint portion J of the plurality of electric wires 2 are collectively joined by thermocompression bonding, the welding equipment becomes large and is not suitable for automation or the like.
