An adhesion method capable of strongly adhering two members without using an adhesive and without impairing a fine structure or optical properties of a joining surface, and a biochemical chip and optical component made by the same are provided. The adhesion method includes step A of forming a coating film 13 of a first film compound having a first photoreactive functional group on a first joining surface 11 of a first member 21, step B of forming a coating film 14 of a second film compound having a second photoreactive functional group on a second joining surface 12 of a second member 22, and step C of bringing the first joining surface 11 into contact by pressure with the second joining surface 12 while setting a coupling agent having at least one coupling reactive group that forms a covalent bond with the first photoreactive functional group and the second photoreactive functional group by light irradiation to be in contact with the first and second photoreactive functional groups, and conducting light irradiation to form covalent bonds.
