A method of manufacturing electrical parts is provided, which method comprises the steps of: forming a photoresist on a part of the surface of a substrate; forming a metal layer on the surface of the substrate after the photoresist has been formed; removing a part of the metal layer; removing a metal oxide film formed on the: surface of the metal layer as a result of removing a part of the metal layer; and removing the photoresist. With this method the contact resistance on the surfaces of the electrical parts can be decreased.
