Abstract
Provided is a block polymer including two or more polymer block As each having a value β of 0.20 or less and a functional group F containing at least one element selected from a group consisting of nitrogen, silicon, oxygen, and sulfur in a part or all of terminals of the two or more polymer block As, in which the block polymer has a value α of 0.75 or more, when p, q, r and s are defined as a component proportion (molar proportion) of a structural unit represented by Formula (1), a component proportion of a structural unit represented by Formula (2), a component proportion of a structural unit represented by Formula (3), and a component proportion of a structural unit represented by Formula (4), in the polymer, respectively.
