できる。As is apparent from the above description, according to the present invention, the temporarily tied wire harness can be directly connected to an electric connection box containing an internal circuit and assembled without a connector. . Therefore, as compared with the case where a terminal is crimp-connected to a wire terminal of a conventional wire harness, the terminal is inserted into a connector, and this connector is fitted into a connector accommodating portion of an electric connection box and connected to an internal circuit, The number of parts can be greatly reduced, such as the elimination of terminals and connectors.
