Method of adhering adherends

A method of adhering adherends, comprising (i) providing at least two adherends, at least one of which is made of a flexible material, (ii) joining said adherends together to form a structure using a heat-resistant adhesive composition comprising mainly a polycarbodiimide resin, an epoxy resin and a curing agent for the polycarbodiimide resin, wherein the proportions of the epoxy resin and the curing agent for the polycarbodiimide resin are 1 part by weight or more and 0.1 part by weight or more, respectively, per 100 parts by weight of the polycarbodiimide resin, such that said structure exhibits an adhesive strength of about 10 and a thermal stability of its adhesive strength of at least 8 at 300° C. as measured according to JIS K 5400.
