摘要：
A number of steps is reduced by manufacturing an electrode pad connecting a liquid discharge head to an external wiring by the same step of a common wiring for supplying an electric power to a discharge energy generating portion. A number of manufacturing steps of a head is reduced by forming a substrate for a liquid discharge head having an electrode pad and a common wiring for supplying an electric power to a discharge energy as a metal film made of the same material as the electrode pad in accordance with a plating in a step of forming the common wiring of the metal film in accordance with a plating.
