摘要： The invention relates to a stamper in which an oxide film having a fine concave-convex structure made up of a plurality of fine pores having an aspect ratio represented by [the depth of the fine pores/the average interval between the fine pores] of 1 to 4 is formed on the surface of an aluminum base material which is made of aluminum having a content of Ti of 150 ppm to 500 ppm, a content of B or C of 1 ppm to 50 ppm and a purity of 99.9% or more. According to the invention, it is possible to provide a low-cost stamper in which the emergence of a pattern derived from the traces of crystal grains on the surface of the oxide film is suppressed, an article having a favorable appearance, which is manufactured using the above stamper, and a method for manufacturing the above.

摘要： The resin optical component mold includes a first mold and a second mold for defining a cavity for molding a resin optical component having a minutely concavo-convex shaped surface, on which a plurality of minute concave or convex portions in units of submicrons is formed, by injection molding light transmitting resin. A master mold 36 formed of an inorganic oxide layer having a minutely concavo-convex shaped surface 36a, on which a concavo-convex shape complementary to the concavo-convex shape formed on the minutely concavo-convex shaped surface of the resin optical component is formed, is provided on the internal surface of the first mold.
