Abstract:
1. A printed circuit board comprising: a base insulating layer; a plurality of signal lines arranged on said base insulating layer, each signal line including a first end, a second end and a wide part between the first end and the second end, the wide parts of the plurality of signal lines arranged in a staggered manner on the base insulating layer; a cover insulating layer that is provided on said base insulating layer so as to cover at least said wide parts of said plurality of signal lines; and a conductive layer that is provided on said cover insulating layer, wherein each of the plurality of signal lines includes a capacitive element, the capacitive element comprising the respective wide part, the cover insulating layer and the conductive layer, such that when a signal is transmitted by a signal line, a harmonic of the signal is removed by the capacitive element of that signal line.
