Patent ID: 8416029

Claim:
A transmission noise suppressing structure comprising: a power supply line and a signal transmission line which are disposed apart from each other on a same surface; a ground layer which is disposed apart from said power supply line and said signal transmission line so as to face said power supply line and said signal transmission line; and a resistive layer which is disposed apart from said power supply line and said ground layer so as to face said power supply line and said ground layer, wherein said resistive layer has an area (I) which faces said power supply line and an area (II) which does not face said power supply line, and said resistive layer and said signal transmission line are apart from each other in a width direction of said power supply line, wherein a width W 1 of said power supply line in the width direction of said power supply line and a width W 2 of said resistive layer in the width direction of said power supply line satisfy Expression (1-1), W 1 <W 2 (1-1).
