Abstract
To provide a method for producing a lens member with which an intended lens shape can be formed on an arbitral substrate, and a lens member and a curved surface shape pattern which are produced by the said method. Also to provide a resin film for forming a curved surface shape pattern with which a lens can be formed. [Solution] A method for producing a lens comprises: Step A in which a laminate body comprising a substrate, a resin layer for forming a curved surface shape disposed on the substrate, and a resin layer for forming a columnar member disposed between the substrate and the resin layer for forming a curved surface shape is formed; Step B in which the resin layer for forming a columnar member and the resin layer for forming a curved surface shape are etched to form a columnar laminate part comprising a columnar member and a member for forming a curved surface shape on the substrate; and Step C in which the member for forming a curved surface shape is heated to cause thermal sagging thereby forming a lens.
