    摘要: A printed wiring board includes an insulating layer, conductive layers respectively formed into predetermined circuit patterns on the upper and lower surfaces of at least the insulating layer, and a conducting section formed in a portion of the insulating layer so as to enable electrical connection between the upper and lower conductive layers. A thickness of the insulating layer is varied to change the electric characteristics of the printed wiring board according to a circuit configuration of the conductive layers.
