CONDUCTION NOISE SUPPRESSING STRUCTURE AND WIRING CIRCUIT BOARD

摘要

PROBLEM TO BE SOLVED: To provide a conduction noise suppressing structure which can suppress conduction noise transmitted through a power supply line and reduce signal transmission line crosstalk.

SOLUTION: The conductive noise suppressing structure is provided with: a power supply line 11 and a signal transmission line 12 arranged on the same surface by being separated apart from each other; a ground layer 13 arranged to face the power supply line 11 and the signal transmission line 12 by being separated apart from them; and a resistive layer 14 arranged to face the power supply line 11 and the ground layer 13 by being separated apart from them. The width of the resistive layer 14 is larger than the width of the power supply line 11 in the width direction of the power supply line 11, and the resistive layer 14 and the signal transmission line 12 are separated apart from each other in the width direction of the power supply line 11.
