A block copolymer includes an end group, a block that binds to the end group, and a block that does not bind to the end group. The block that does not bind to the end group contains at least one non-crosslinkable constitutional unit represented by the formula (X) and/or at least one non-crosslinkable constitutional unit represented by the formula (Z). At least one of formulas (i) X>X, (ii) Z>Zand (iii) X+Z>X+Zis satisfied when the total number of non-crosslinkable constitutional units represented by formulas (X) and (Z) in the block that does not bind to the end group are represented by Xand Z, respectively, and the total number of non-crosslinkable constitutional units represented by formulas (X) and (Z) in the block that binds to the end group are represented by Xand Z, respectively.
