摘要：
The invention provides a multilayer printed wiring board including: a power supply wiring layer and a ground wiring layer provided so as to oppose each other via an insulation layer; mounted integrated circuits; and decoupling capacitors mounted in proximity to the integrated circuits and connected between the power supply wiring layer and the ground wiring layer to absorb noise from the integrated circuits. The power supply wiring layer includes through holes for connecting the decoupling capacitors to the power supply wiring layer and has a polygonal form formed by straight lines which link some of the through holes.
