Patent ID: 8334051

Claim:
A method of adhering a first joining surface of a first member to a second joining surface of a second member, comprising: bringing a first film compound having a first photoreactive functional group at an end of its molecule and a first surface bonding group at another end thereof into contact with the first joining surface to form a covalent bond between the first surface bonding group and a surface functional group of the first joining surface so as to form a coating film of the first film compound on the first joining surface; bringing a second film compound having a second photoreactive functional group at an end of its molecule and a second surface bonding group at another end thereof into contact with the second joining surface to form a covalent bond between the second surface bonding group and a surface functional group of the second joining surface so as to form a coating film of the second film compound on the second joining surface; and bringing the first joining surface having the coating film of the first film compound thereon into contact by pressure with the second joining surface having the coating film of the second film compound thereon while setting a coupling agent having at least one first coupling reactive group that forms a covalent bond with the first photoreactive functional group by light irradiation and at least one second coupling reactive group that forms a covalent bond with the second photoreactive functional group by light irradiation to be in contact with the first functional photoreactive group and the second photoreactive functional group, and conducting light irradiation to form covalent bonds: between the first photoreactive functional group and the first coupling reactive group; and between the second photoreactive functional group and the second coupling reactive group, wherein the first photoreactive functional group and the second photoreactive functional group are selected from the group consisting of a chalconyl group and a cinnamoyl group, or wherein the first photoreactive functional group and the second photoreactive functional group are selected from a diacetylene group.
