Patent ID: 8168255

Claim:
A coating method of dripping and applying a coating liquid on a coating surface of an object to be coated, while rotating the object to be coated, the coating surface being formed into a convex curved shape, the method comprising: dripping the coating liquid in a ring shape in a vicinity of an outer circumference on the coating surface of the object to be coated, and thereafter dripping the coating liquid in a spiral shape toward a geometrical center or an optical center of the object to be coated from the vicinity of the outer circumference, wherein a rotational speed of the object to be coated at a time of dripping the coating liquid in the ring shape, is set to be a smaller value than a rotational speed of the object to be coated at a time of dripping the coating liquid in the spiral shape, and wherein the rotational speed of the object to be coated is constant when the coating liquid is dripped in the ring shape, and the rotational speed of the object to be coated is constant when the coating liquid is dripped in the spiral shape.
