Patent ID: 8261438

Claim:
A method for forming a metal pattern comprising: (a1) a step of providing, on a substrate, a polymer layer that comprises a polymer containing a functional group that interacts with a metal ion or a metal salt, the polymer directly chemically bonding to the substrate; (a2) a step of applying a metal ion or a metal salt to the polymer layer; (a3) a step of reducing the metal ion or the metal salt to form a conductive layer having a surface resistivity of from 5 Ω/square to 100 kΩ/square; (a4) a step of forming a pattern-shaped resist layer on the conductive layer having a surface resistivity of from 5 Ω/square to 100 kΩ/square; (a5) a step of forming, in a region where the resist layer is not formed, a metal pattern by electroplating; (a6) a step of separating the resist layer; (a7) a step of removing the conductive layer formed in the step (a3) from a region that has been protected by the resist layer; and (a8) a step of performing a hydrophobilizing treatment at the polymer layer that has been provided in the step (a1) and that is present in the region from which the conductive layer has been removed in the step (a7).
