Molding Method And Molding Device

摘要

A shaping method and a shaping device are provided which can easily and inexpensively form a curved face in a film including a micropattern. A shaping method is for forming, in a predetermined shaping-target area of a film including a patterned face with a micropattern, and a rear face opposite to the patterned face, a curved face beyond the thickness of the film, and includes a fixing step for fixing an outer edge of the shaping-target area of the film by fixing means, a first heating step for heating the film 20 by heating means 95, and a pressure adjusting step for producing a predetermined pressure difference between both faces of the film by the pressurizing means in such a way that pressure at a side where the film is fixed in the fixing step becomes small to form a pre-curved face.

1. A shaping method for forming, in a predetermined shaping-target area of a film comprising a patterned face including a micropattern, and a rear face opposite to the patterned face, a curved face beyond a thickness of the film, the method comprising:
a fixing step for fixing an outer edge of the shaping-target area of the film; and a pressure adjusting step for producing a predetermined pressure difference between both faces of the resin film in such a way that a pressure of a fluid at a side where the resin film is fixed in the fixing step becomes relatively small.
