Patent ID: 8597460

Claim:
An optical component comprising: a first member and a second member, wherein: on a first joining surface of the first member, a first coating film of a first film compound having a first functional group at an end of its molecule and covalently bonded to the first joining surface at another end thereof; on a second joining surface of the second member, a second coating film of a second film compound having a second functional group at an end of its molecule and covalently bonded to the second joining surface at another end thereof; the first functional group and the second functional group are covalently bonded to each other via bonds formed by coupling reactions: between the first functional group and a coupling agent having at least one first coupling reactive group configured to form a covalent bond by a coupling reaction with the first functional group and at least one second coupling reactive group that is configured to form a covalent bond by a coupling reaction with the second functional group; and between the second functional group and the coupling agent, the first joining surface is adhered to the second joining surface via the formed bonds; the first functional group comprises an epoxy group; the second functional group comprises an epoxy group; and the coupling agent comprises an imidazole.
