Since the resin molding is performed in a state where the connecting portion of the cable is positioned by using the core having the base piece and the pair of side wall pieces, no positional displacement of the terminal or the electric wire occurs.
As a result, excellent waterproofness and insulating properties can always be stably ensured. Also, it is possible to reduce the dimension of the mold section in the thickness direction. Furthermore, since the core is inexpensive and the man-hour required for the resin molding is small,
Cost reduction can be achieved.
