SHAPING METHOD

摘要

A shaping method in which a shaped object such as a lens can be produced with higher accuracy than in conventional techniques.  A shaped object, e.g., a lens array or a die for nanoimprinting, is produced by repeatedly performing a transfer step a plurality of times, the transfer step comprising: a deformation step in which a photocurable composition comprising an epoxy compound and a polymerization initiator is brought into contact with a transfer object (62) having a shape to be transferred that is either the same as the shape of an aspherical lens part (312) or the reverse of the shape of an aspherical lens part (312), and the photocurable composition is thereby deformed so as to conform to the shape to be transferred of the transfer object (62); a curing step in which at least the deformed portion of the deformed photocurable composition is cured by irradiation with light using a light irradiator (60); and a separation step in which the photocurable composition that has been cured is separated from the transfer member.
