Claim 12:
13. A method of manufacturing a body comprising stacked substrates, the method comprising:
a first step of forming, on a first substrate, a film comprising a compound (A), which has a cationic functional group containing at least one of a primary nitrogen atom or a secondary nitrogen atom;
a second step of providing, on the film, a cross-linking agent (B), which has three or more —C(═O)OX groups in a molecule, in which from one to six of the three or more —C(═O)OX groups are —C(═O)OH groups and which has a weight average molecular weight of from 200 to 600, X being a hydrogen atom or an alkyl group having from 1 to 6 carbon atoms;
a third step of layering a second substrate on a surface on which a film comprising the compound (A) and the cross-linking agent (B) is formed; and
a heating step of heating the film comprising the compound (A) and the cross-linking agent (B) to a temperature of from 70° C. to 450° C., thereby forming an adhesion layer comprising a reaction product of the compound (A) and the cross-linking agent (B),
wherein the compound (A) comprises a compound having a siloxane bond (Si—O bond) and an amino group and having a weight average molecular weight of from 130 to 10,000.
