Definitions
- the present invention relates to a mold manufacturing method.
- a method for forming a fine pattern light is applied to a photocurable resin while a mold having a pattern obtained by inverting a desired fine pattern is pressed against a film made of a liquid photocurable resin.
- a method of forming a desired fine pattern by irradiating and curing a photocurable resin is known as a V-like nanoimprint method (see Patent Documents 1 to 3).
