TRANSMISSION CABLE AND PROCESS FOR PRODUCING SAME

摘要

Disclosed is a transmission cable wherein a plurality of signal lines (2) are formed on one side of an insulating layer (1) and a ground line (3) is formed between the signal lines (2). The ground line (3) is electrically connected with a shield layer (4) formed on the rear surface of the insulating layer (1) through a metal bump (5) embedded in the insulating layer (1). Alternatively, insulating layers (1, 6) and shield layers (4, 7) may be formed on the opposite sides of the signal lines (2) and the ground line (3). In this case, the ground line (3) is electrically connected with the shield layers (4, 7) respectively through metal bumps (5, 8) on the opposite sides. Consequently, a highly reliable transmission cable capable of high rate transfer and large capacity transfer can be provided.
