A method of manufacturing an optical lens device includes the steps of forming a lens barrel into the shape of a quadrangular prism having corners that have a shape having a radius of curvature or that are chamfered, and installing a lens into the lens barrel; disposing in parallel a plurality of the lens barrels in which a plurality of the lenses are installed; masking the lens at one side face of each lens barrel disposed in parallel, and the vicinity of the lens; and depositing a gold layer by sputtering on the one side face of each masked lens barrel, including the corners.
