ABSTRACT:
A transmission cable and method for manufacturing same are provided. A plurality of signal lines are formed on one side of an insulating layer and ground lines are formed between the signal lines. The ground lines are electrically connected with a shield layer formed on a back surface of the insulating layer through metal bumps formed and embedded in the insulating layer. Insulating layers and shield layers may be formed on opposite sides sandwiching the signal lines and the ground lines. In this case, the ground lines are electrically connected with the shield layers, respectively, through metal bumps on both sides thereof. Consequently, a highly reliable transmission cable capable of high rate transfer and large capacity transfer can be provided.
