Abstract
A method for manufacturing a wiring board that includes preparing a substrate including an insulating resin and a metal member having an anti-rust layer formed on a surface thereof that is arranged so as to face a second surface of the insulating resin. The method includes forming a bottomed hole by irradiating a first laser beam from a first surface side of the insulating resin. The bottomed hole penetrates the insulating resin and has an inner bottom surface that is the surface of the metal member. The method also includes removing the anti-rust layer formed on the surface of the metal member in the inner bottom surface of the bottomed hole, injecting a conductive paste into the bottomed hole and applying the conductive paste to the first surface of the insulating resin so as to have a wiring continuous with the injected conductive paste, and curing the conductive paste.
