Method for producing mold for transferring fine pattern, method for producing substrate having concave-convex structure using same, and method for producing organic el element having said substrate having concave-convex structure

A method for producing a mold for transferring a fine pattern, comprising:

• a step of coating a surface of a base member with a solution containing a block copolymer and polyalkylene oxide, the block copolymer being composed of at least first and second polymer segments;
• a solvent phase-separation step of phase-separating the block copolymer contained in the solution, with which the surface of the base member is coated, under a presence of vapor of an organic solvent so as to obtain a block copolymer film of the block copolymer, the block copolymer film having a concave-convex structure on a surface thereof and a horizontal cylinder structure in an interior thereof;
• a step of forming a seed layer on the concave-convex structure of the block copolymer film;
• a step of stacking a metal layer on the seed layer by electroforming;
• and
• a step of releasing the base member, on which the concave-convex structure is formed, from the metal layer.
