Abstract: A coating apparatus, which coats only the outer circumferential edge face of a workpiece with film-forming liquid, even if the workpiece is a non-circular thin lens or the like, a rotating mechanism is configured so that a workpiece and an imitating form having the same shape as the outer shape of the workpiece can rotate synchronously around the same rotation axis center, a coating mechanism includes a pressing roller that can rotate with the imitating form while being pressed against an outer circumferential edge face of the imitating form, and a coating part including a coating roller which, while being pressed against the outer circumferential edge face of the workpiece, rotates with the workpiece and applies the film forming liquid to the outer circumferential edge face of the workpiece, a rotary transmission unit that synchronously rotates the pressing roller and the coating roller having the same outer shape.
