An object of the present invention is to provide a multilayer printed circuit board to increase the impedance of the via hole.
A multilayer printed wiring board P is provided with a ground layer L1 and via holes V1. Ground layer L1 includes a wiring layer L11 and the first impedance adjustment layer L12. Wiring layer L11 is a configuration in which conductive lines L114 are arranged in the opening L112 and passage L113 provided a solid conductor L111. Adjusting layer L12 is a structure in which openings L122 is provided in a solid conductor L121. Via holes V1 is connected to the opening L112 and and conductive lines L114 provided a ground layer L1 and the insulating layer L2 to be positioned in the opening L122. Distance is R1 <distance R2. The distance R1 is a distance Y-Y 'direction from the outline α1 opening L112 until the via hole V1. The distance R2 is the distance Y-Y 'direction from the outline α2 opening L122 until the via hole V1.
