Detailed Description

In order to make the technical field of the present invention better understand, the present invention is further described in detail with reference to the accompanying drawings and embodiments.

As shown in fig. 1-2, an embodiment of the present invention provides an FFC with a fuse, including two layers of insulating films 1, and a conductor layer 2 disposed between the two layers of insulating films, wherein the conductor layer 2 is composed of a plurality of metal strips 201 parallel to each other.
