Abstract: A method for producing a wiring board, including: a step of pretreating the surface of a metal layer exposed into an opening by bringing the surface into contact with a pretreatment liquid at a predetermined pretreatment temperature; and a step of forming a copper plating layer on the metal layer by electrolytic plating. The resist layer and the pretreatment liquid are selected such that a mass change rate of the resist layer when the resist layer before being exposed and developed is immersed in the pretreatment liquid is ?2.0% by mass or more. The mass change rate is a value calculated by Expression: Mass change rate (% by mass)={(W1?W0)/W0}×100. W1 is the mass of the resist layer after a laminated body including a resist layer 3 and a copper foil is immersed in the pretreatment liquid at the pretreatment temperature for 30 minutes.
