An object of the invention is to provide a multi-core conductive wire having the small number of manufacturing processes and a terminal with high strength, and a method of manufacturing the multi-core conductive wire. The multi-core conductive wire is provided with a terminal, at the end portion thereof, where individual strands of the multi-core conductive wire are entangled with each other and the terminal is molded by subjecting to pressure-molding. A method of manufacturing a multi-core conductive wire comprises a step of processing the multi-core conductive wire into a state where individual strands of the multi-core conductive wire are partially entangled with each other; a step of temporarily molding the processed portion; and a step of further applying pressure to the temporarily molded portion for pressure-molding or plastic working.
