Printed wiring board with two ground planes connected by resistor

摘要

A printed wiring board is provided with a ground wiring structure corresponding to a signal wiring structure. The ground wiring structure is furnished with a first wiring layer located on a first side surface of an insulating layer along with the signal wiring layer, and a second wiring layer located on another side surface of the insulating layer and sandwiching the insulating layer against the signal wiring layer. A resistor is interposed between the first wiring layer and the second wiring layer.
