A method for producing a film includes: coating a surface of a substrate with a composition containing a polymer having a structural unit represented by formula (1) and having a number average molecular weight of 13000 or more and a solvent, heating a coating film formed by the coating, and removing, with a rinsing liquid, a part of the coating film after the heating, wherein the rinsing liquid to be used contains a basic compound. In the formula (1), Yis a single bond, &#x2014;CO&#x2014;NR&#x2014;, a divalent aromatic ring group, a divalent group containing &#x2014;O&#x2014;, or a divalent group containing &#x2014;CO&#x2014;NR&#x2014;. Ais a single bond, &#x2014;O&#x2014;, &#x2014;S&#x2014;, or &#x2014;NR&#x2014;. Ris a hydrogen atom, a monovalent hydrocarbon group, a monovalent halogenated hydrocarbon group, or a monovalent group having a heterocyclic structure.

Method for producing film

A method of producing a substrate includes: applying a composition on a metal basal plate to form a coating film; and forming a metal-containing layer on at least a part of the coating film. The composition contains a solvent, and a polymer having a first terminal structure and a second terminal structure in a single molecule. Each of the first terminal structure and the second terminal structure is at least one selected from the group consisting of a structure represented by formula (1) and a structure represented by formula (2). Aand Aeach independently represent a monovalent group having a functional group capable of forming a chemical bond with a metal atom. Lrepresents &#x2014;S&#x2014;, &#x2014;NR&#x2014;, or &#x2014;NA-, wherein Arepresents a monovalent group having a functional group capable of forming a chemical bond with a metal atom.
