Abstract:
1. An electrical connection structure for a wiring member comprising: a main board; a daughter board; and a flat cable which electrically connects the main board and the daughter board; wherein the flat cable includes: a signal line which transfers signal and is electrically connected to the main board and the daughter board, a first conductive line which connects with a predetermined potential and connects the main board and the daughter board, a second conductive line which is arranged in one side portion of the flat cable, wherein the second conductive line includes: one end of the second conductive line is electrically connected to the first conductive line in the daughter board, and another end of the second conductive line which electrically isolates the main board, and a third conductive line, and wherein the third conductive line is arranged in an other side portion of the flat cable, and the third conductive line includes one end of the third conductive line which is electrically connected to the first conductive line in the main board, and another end of the third conductive line which electrically isolates the daughter board, wherein a high-frequency current which flows from the main board side to the daughter board side via the first conductive line flows from the daughter board side toward the main board by using the second conductive line and the third conductive line.
