The present invention discloses a flexible cable arrangement method by making conducting layer and dielectric layer directly on extension part of main cable to change distance between adjacent conductor lines and have effect of jumper. The structure comprises the main cable, conducting layer and dielectric layer, wherein the main cable including upper dielectric layer, under dielectric layer, anda plurality of conductors set between upper and under dilectric layer; an extension part protruding in the upper dilectric layer is mounted on the under dilectric layer; contact point on one end of the conductor exposed on upper dilectric and set above the extension part; conductor layer set above extension part and electrically connected with the contact point of conductor; dilectric layer set on the extension part covering conductor layer and contact point of conductor.
