Claim:
1. A method of producing a structure containing a phase-separated structure, comprising: coating an undercoat agent on a substrate to form a layer formed of the undercoat agent; forming a layer containing a block copolymer having a block of a structural unit derived from an (α-substituted) acrylate ester and a block of a polyhedral oligomeric silsesquioxane structure-containing structural unit or a structural unit derived from a styrene or derivative thereof on the layer formed of the undercoat agent; and phase-separating the layer containing the block copolymer, the undercoat agent comprising: a copolymer having a structural unit (ba0-1) represented by general formula (ba0-1) and a structural unit (ba0-3) selected from structural units represented by general formulae (ba0-3-1) to (ba0-3-4) shown below, or a copolymer having a structural unit (ba0-2) represented by general formula (ba0-2) and the structural unit (ba0-3): wherein in the formula (ba0-1), R represents a hydrogen atom, an alkyl group of 1 to 5 carbon atoms or a halogenated alkyl group of 1 to 5 carbon atoms, R wherein in the formula (ba0-2), R represents a hydrogen atom, an alkyl group of 1 to 5 carbon atoms or a halogenated alkyl group of 1 to 5 carbon atoms, and R wherein R represents a hydrogen atom, an alkyl group of 1 to 5 carbon atoms or a halogenated alkyl group of 1 to 5 carbon atoms, R b represents a hydrogen atom or an alkyl group of 1 to 5 carbon atoms, Y 01 represents a divalent linking group, Y 02 represents a divalent linking group, Y 03 represents a single bond or a divalent linking group, and X 01 to X 04 each independently represents a carboxy group, a hydroxyl group, a cyano group, an azido group, an amino group, a trialkoxysilyl group, a dialkoxysilyl group, a monoalkoxy silyl group, a lactone-containing cyclic group, groups represented by the following formula (ba0-3-1′-r1) to (ba0-3-1′-r2), an ether-containing cyclic group, or a cyclooctatrienyl group: wherein Ra′ 201 represents a hydrogen atom, an alkyl group of 1 to 10 carbon atoms, n is an integer of 1 to 3, and * represents a bond.
