<P>PROBLEM TO BE SOLVED: To reduce misalignment between optical axes of optical elements caused by curing shrinkage of an energy curing adhesive. Ž<P>SOLUTION: An ultraviolet irradiation device 13 is provided in an adhesion device for an optical element, and irradiates a workpiece W composed of a lower lens 1 and an upper lens 10 layered through an ultraviolet curing type adhesive 12a with ultraviolet light 13d, so that the lower lens 1 and the upper lens 10 are made to adhere to each other by curing the ultraviolet curing type adhesive 12a. In the device 13, by providing an optical diaphragm 13c lying in an irradiation path of the ultraviolet light 13d between an ultraviolet light source 13b emitting the ultraviolet light 13d and the workpiece W, and controlling ON/OFF of the intensity and irradiation of the ultraviolet light 13d with which the workpiece W is irradiated, misalignment between the optical axis 1a of the lower lens 1 and the optical axis 10a of the upper lens 10 caused by the curing shrinkage of the ultraviolet curing type adhesive 12a is prevented.
