Flexible flat cable

A flexible flat cable including a plurality of conductive wires (15) disposed between an upper film (11) and a lower film (13), wherein the conductive wires (15) are fixed by a first thermal bonding resin (12) applied to a lower surface of the upper film (11), an air gap (16) is formed between the conductive wires (15) and between the lower film (13) and the conductive wire (15), and a side end of the upper film (11) and a side end of the lower film (13) are bonded by the first thermal bonding resin (12).

A flexible flat cable including a plurality of conductive wires (15) disposed between an upper film (11) and a lower film (13), wherein the conductive wires (15) are fixed by a second thermal bonding resin (14) applied to the lower film (13), an air gap (16) is formed between the conductive wires (15) and between the upper film (11) and the conductive wire (15), and a side end of the upper film (11) and a side end of the lower film (13) are bonded by the second thermal bonding resin (14).

A flexible flat cable including a plurality of conductive wires (115) disposed between an upper film (111) and a lower film (113), wherein the conductive wires (115) are fixed by a first thermal bonding resin (112) of the upper film and a second thermal bonding resin (114) of the lower film, a first air gap (116) is formed between the conductive wires, a second air gap (126) is formed by removing the first thermal bonding resin on a partial upper surface of each of the conductive wires, a third air gap (136) is formed by removing the second thermal bonding resin on a partial lower surface of each of the conductive wires, and a side end of the upper film and a side end of the lower film are bonded by the first thermal bonding resin (112) and the second thermal bonding resin (114).

A flexible flat cable including a plurality of circular conductive wires (1115) disposed between an upper film (111) and a lower film (113), wherein the circular conductive wires are fixed by a first thermal bonding resin (112) of the upper film and a second thermal bonding resin (114) of the lower film, the first thermal bonding resin of the upper film and the second thermal bonding resin of the lower film are partially removed to form an air gap (1116) between the circular conductive wires such that the air gap is shielded from the circular conductive wires, and a side end of the upper film and a side end of the lower film are bonded to each other by the first thermal bonding resin (112) and the second thermal bonding resin (114).
