An object of the present invention is to provide a method for producing a substrate, a composition, and a polymer capable of easily producing a substrate having a metal-containing layer on the surface of the metal substrate. The present invention is a method for manufacturing a substrate including a step of coating a composition on a metal substrate and a step of forming a metal-containing layer on at least a part of the coating film formed by the coating step. The composition contains a polymer having a first-terminal structure and a second-terminal structure on the same molecule as the solvent, and the first-terminal structure and the second-terminal structure are represented by the following formulas (1), respectively. It is characterized in that it is at least one selected from the group consisting of the above-mentioned structure and the structure represented by the following formula (2). In the following formula (1), A 1 is a monovalent group containing a functional group capable of chemically bonding with a metal atom. In the following formula (2), L 2 is, -S -, - NR- or -NA 22 - a. A 2 and A 22 are monovalent groups containing a functional group capable of chemically bonding with a metal atom. [Selection diagram] None |
