摘要：
A printed wiring board having a conductor circuit comprising a copper layer adjacent to an insulating layer and an electroless gold plating, wherein the insulating layer has ten-point mean surface roughness (Rz) of 2.0 μm or less is provided. According to the present invention, there is no such a defect that gold plating is deposited on a resin, and fine wiring formation with accuracy is realized.
