Abstract: A manufacturing process of an electrode substrate includes a step of forming a protective layer so as to cover a conductor pattern by applying raw material liquid discharged as droplets to an upper surface of a substrate in a first region and a second region of the upper surface of the substrate. At this time, an application amount of the raw material liquid per unit area in the second region is made smaller than an application amount of the raw material liquid per unit area in the first region, so that an average film thickness of the protective layer of a portion formed in the second region is made smaller than an average film thickness of the protective layer of a portion formed in the first region.
