Abstract: Provided are a flexible flat cable and a method of producing the same. The flexible flat cable includes a plate-shaped first insulation portion comprising an insulating material; a first ground, a second ground, and a third ground disposed at predetermined intervals on the first insulation portion; at least one first signal transmission line positioned between the first ground and the second ground and disposed on the first insulation portion; at least one second signal transmission line positioned between the second ground and the third ground and disposed on the first insulation portion; a first second insulation portion disposed on at least a portion of the first ground and at least a portion of the at least one first signal transmission line and the second ground; a second insulation portion disposed on at least a portion of the second ground and at least a portion of the at least one second signal transmission line, and the third ground; a conductive adhesive layer configured to enclose the first insulation portion, the first second insulation portion, and the second insulation portion; and a shielding portion comprising a shielding material adhered to an outside of the conductive adhesive layer. Therefore, by improving shielding efficiency of a plurality of signal transmission lines, while having good electromagnetic interference and crosstalk characteristics, a plurality of signals can be simultaneously transmitted.
