A polymer thin film in which cylindrical phases are distributed in a continuous phase and are oriented in a pass-through-direction of the film includes at least: a first block copolymer including at least a block chain A 1 , as a component of the continuous phase, composed of polymerized monomers a 1 , and a block chain B 1 , as a component of the cylindrical phases, composed of polymerized monomers b 1 ; and a second block copolymer including at least a block chain A 2 , as a component of the continuous phase, composed of polymerized monomers a 2 , and a block chain B 2 , as a component of the cylindrical phases, composed of polymerized monomers b 2 , with the second copolymer having a degree of polymerization different from that of the first copolymer. A film thickness of the polymer thin film and an average center distance between adjacent cylindrical phases have a relation represented by a predetermined expression.
