Abstract: First, a photosensitive resin film is formed on a substrate. Then, the resin film is patterned by photolithography into a collection of quadrilateral prisms that are arranged discretely. Then, the individual quadrilateral prisms are deformed so as to be undulated gently by performing a heat treatment. Thereafter, a resin film is applied to the collection of deformed quadrilateral prisms, whereby flat gap portions between the discrete quadrilateral prisms are filled in and curved surfaces are formed there. Finally, a metal film is formed on the collection of gently undulated quadrilateral prisms.
