A block copolymer including a first block consisting of a polymer having a repeating structure of a structural unit (u1) containing no silicon atom, and a second block consisting of a polymer having a repeating structure of a structural unit (u2) containing a silicon atom, the second block containing a block (b21) consisting of a polymer having a repeating structure of a structural unit (u21) represented by general formula (u2-1) shown below, and the volume ratio of the first block, based on all blocks constituting the block copolymer being 42 to 44 vol %:  In which Rrepresents an alkyl group, a halogenated alkyl group, a hydrogen atom, or an organic group having a polar group; and Ris a group derived from a compound represented by formula SHR, wherein Rrepresents a hydrocarbon group having 1 to 5 carbon atoms optionally having a substituent.

Method of producing block copolymer capable of creating specific structure pattern

A block copolymer including a first block consisting of a polymer having a repeating structure of a structural unit (u1) containing no silicon atom, and a second block consisting of a polymer having a repeating structure of a structural unit (u2) containing a silicon atom, the second block containing a block (b21) consisting of a polymer having a repeating structure represented by general formula (u2-1), and a block (b22) consisting of a polymer having a repeating structure of a structural unit (u22) containing a silicon atom, and the block (b22) is positioned between the first block and the block (b21) (wherein Rrepresents an alkyl group, a halogenated alkyl group, a hydrogen atom, or an organic group having a polar group; and Rrepresents an organic group having a polar group). 

Block copolymer and method of producing the same, and method of producing structure containing phase-separated structure
