Abstract
A ridgy resin film made of a resin is formed. On a flat substrate, a first concave and a second concave are formed such as to be spaced a given distance apart from each other. Then, a resin liquid is supplied onto a land being part of the substrate exposed between the first and second concaves. Due to its surface tension, the resin liquid supplied onto the land bulges, and a ridgy resin film even in width is formed by curing the resin liquid in this state. Along the edges of the openings of the first concave and the second concave, ridges are formed. Since the resin liquid is supplied onto the land between the ridges, it does not drip nor overflow.
