Abstract
This invention permits reduction in space between conductors in a shielded flat cable, as well as improvement in shielding ability and cost savings of the shielded flat cable. The shielded flat cable comprises a cable body 8 including a base film 3, circuit conductors 1, and a ground conductor 2. The circuit conductors 1 are disposed in the upper surface of the base film 3 in a parallel relationship with one another. A lower cover layer film 4B is attached to the upper surface of the base film 3. The ground conductor 2 is disposed on the lower cover layer film 4B in a parallel relationship with the circuit conductors 1. An upper cover layer film 4A is placed over the ground conductor 2 and the lower cover layer film 4B. An area 7 having no upper cover layer film 4A is provided in the cable body. The area 7 having a predetermined width extends transversely of the cable body 8. A shield tape 5 is wrapped around the cable body so as to shield the cable body. The ground conductor 2 and the shield tape 5 are electrically connected with each other in surface-to-surface contact through the area 7 having no upper cover layer film.
