The peeled cover tape 6 is wound on the ring and then discarded. On the other hand, the carrier tape 3 that has finished supplying the electronic component 5 is cut into short pieces and then discarded.

[0006]

As described above, after the supply of the electronic parts 5 is completed, the auxiliary materials such as the carrier tape 3 and the cover tape 6 which constitute the electronic part series 1 are discarded. . Therefore, the resources related to such auxiliary materials are wasted. Further, the cost of these sub-materials occupies a relatively high ratio with respect to the cost of the entire electronic component series 1, so that the waste of the sub-materials results in a cost reduction of the electronic component series 1. It also leads to a rise.

[0007] Therefore, an object of the present invention is to provide a series of electronic components which can effectively utilize resources and can expect cost reduction accordingly.
