Method for forming metal pattern, metal pattern and printed wiring board

摘要

The present invention provides a method for forming a metal pattern comprising a step of forming a polymer layer on a substrate; (a2) a step of applying a metal ion or the like to the polymer layer; (a3) a step of forming a conductive layer by reducing the metal ion or the like; (a4) a step of forming a patterned resist layer on the conductive layer; (a5) a step of forming a metal pattern by electroplating in the regions where the resist layer is not formed; (a6) a step of separating the resist layer; (a7) a step of removing the conductive layer from regions protected by the resist layer; and (a8) a step of performing a hydrophobilizing treatment.
