Abstract
【解決手段】 電源配線層3とグランド配線層2とが平行に配置され、集積回路5〜8と、この集積回路の周辺に配置されてこの集積回路のノイズを吸収すべく電源配線層とグランド配線層との間に接続されたデカップリングコンデンサ9a〜9lとを実装してなる多層プリント配線板1において、電源配線層3が、デカップリングコンデンサ9a〜9lの電源配線層への接続のためのスルーホールを包含し、少くとも一部のスルーホール間を結ぶ直線により形成される多角形とされている。これにより、集積回路のノイズを吸収するためのデカップリングコンデンサ9a〜9lを、電源配線層とグランド配線層との間のノイズを吸収するためのデカップリングコンデンサと兼用することができる。
