Claim Text:
1. A method for producing a mold for minute pattern transfer, comprising: a step of applying a block copolymer solution made of at least a first polymer and a second polymer on a surface of a base member; a step of drying a coating film on the base member; a first heating step for heating the coating film after the drying at a temperature higher than a glass transition temperature of a block copolymer of the block copolymer solution; an etching step for etching the coating film after the first heating step to remove the second polymer so that a concavity and convexity structure is formed on the base member; a second heating step for heating the concavity and convexity structure at a temperature higher than a glass transition temperature of the first polymer; a step of forming a seed layer on the concavity and convexity structure after the second heating step; a step of or stacking a metal layer on the seed layer by an electroforming; and a step of peeling off the base member having the concavity and convexity structure from the metal layer and the seed layer.
