PROBLEM TO BE SOLVED: To prevent a malfunction of a circuit board.SOLUTION: A sheet-like conductor used in a plurality of flexible flat cables for electrically connecting a plurality of circuit boards is folded with multiple sections overlapping sequentially. The flexible flat cables are grounded with the sections interposed. When signals flow in the flexible flat cables, even if a signal high-frequency component leaks from the flexible flat cable, the signal high-frequency component is received by the sheet-like conductor, to flow into earth, and the signal high-frequency component is superimposed on the signal flowing in the flexible flat cable, thereby preventing electromagnetic interference and a malfunction of the circuit board.SELECTED DRAWING: Figure 6 |
