Method for manufacturing wiring board

A method for manufacturing a wiring board in which the adhesion between an underlayer and a seed layer is improved. A diffusion layer in which an element forming the underlayer and an element forming a coating layer are mutually diffused is formed between the underlayer and a wiring portion of the coating layer by irradiating the wiring portion with a laser beam. A seed layer is formed by removing a portion excluding the wiring portion of the coating layer from the underlayer. A metal layer is formed by disposing a solid electrolyte membrane between an anode and the seed layer and applying voltage between the anode and the underlayer. An exposed portion without the seed layer of the underlayer is removed from an insulating substrate.
