摘要:
This invention is to provide a multilayer printed circuit board having excellent appearance and reliability and a method of producing the same, and proposes a build-up multilayer printed circuit board comprising an interlaminar insulating layer 4 comprised of an adhesive for additive process between an inner layer copper pattern 3 provided at its surface with a fine uneven layer 9 and an outer layer copper pattern 6 in which the surface of uneven layer 9 in the inner layer copper pattern 3 is covered with a metal layer containing one or more of metals having an ionization tendency not lower than that of copper but not higher than that of titanium, or a noble metal layer 10, and a production technique therefor.
