Claim:
1. A bonding method, comprising: bonding a substrate and a support for supporting the substrate to each other through an adhesive layer and pressing the bonded substrate and support, wherein an environment in which the pressing is performed has a pressure of 0.1 Pa to 10 Pa and a temperature of 120 to 260° C., wherein the adhesive layer comprises a cycloolefin copolymer or an elastomer resin component, a polymerization inhibitor, a solvent and an entrainer; after bonding and pressing, placing the bonded substrate and support in an environment at atmospheric pressure and a temperature of 120 to 260° C.; and after placing the bonded substrate and support, vacuum heating the bonded substrate and support at a pressure of 0.1 to 10 Pa and a temperature of 120 to 260° C.
