Description

(銅箔)
本発明で用いられる銅箔は、回路基板において用いられる銅箔であれば、特に限定されず、圧延銅箔、電解銅箔のいずれであってもよい。ま、銅箔は、銅と他の金属の合金であってもよい。
銅箔の厚さは、例えば、5〜150μmであってもよく、好ましくは6〜130μm、より好ましくは9〜110μmの範囲であってもよい。
(比較例2)
粗化処理において、亜塩素酸ナトリウム31g/L、水酸化ナトリウム15g/L、およびリン酸三ナトリウム12g/Lを含む黒化処理液を用い、95℃で2分間粗化処理を行う以外は、実施例1と同様にして多層配線板を作製した。粗化処理後の銅箔表面を5000倍で拡大した走査型顕微鏡写真を図5に示す。図5に示すように、銅箔表面にはとげ状の先端を有する突出部が数多く形成されている。
