Abstract: A bundle-of-electric wire container can contain a bundle of electric wire P wound in a loop shape and permit drawing out of the electric wire. Containers can be stacked in a plurality of stages to increase storage efficiency and conveyance efficiency. A bundle-of-electric wire containing space is formed between core pieces and an outer cylinder, and the bundle of electric wire is protected by the outer cylinder. The container is used as one unit for the storage of a bundle of electric wire and to the feeding of the electric wire P through a conveyance. Accordingly, in the manufacturing field of a wiring harness, the bundle of electric wire can be stored and conveyed without losing its shape, for example, and done so efficiently. It is possible to improve the operating efficiency of a manufacturing line by preventing the electric wire from being tangled, for example, at the time of feeding the electric wire as well as to prevent an inferior product from being manufactured.
