A polymer composition comprising:
- a block copolymer which comprises a polymer segment A containing a first monomer unit and a polymer segment B having an absolute value of a surface energy difference with the polymer segment A of 10 mN/m or less and the polymer segment B containing a second monomer unit;
- and
- a random copolymer containing the first monomer unit and the second monomer unit, wherein the second monomer unit in the random copolymer has a volume fraction of 0.3 to 0.7 , and a sum of volume fractions of the first monomer unit and the second monomer unit in the random copolymer is 1,
- wherein the random copolymer is contained in a ratio of 1 vol % to 50 vol % based on a total volume of the block copolymer and the random copolymer, and
