Abstract:
Semi-columnar shaped convex portions are formed on external areas of respective resin lens plates. One semi-columnar shaped convex portion and two semi-columnar shaped convex portions are formed at the top surface of the bottom resin lens plate and the bottom surface of the top resin lens plate, respectively. Then, the top resin lens plate and the bottom resin lens plate are temporarily fixed by matching the one semi-columnar shaped convex portion into the area between the two semi-columnar shaped convex portions. Then, after the temporal fixing, the joints of the resin lens plates are heated and melted to form a welding portion. Then, the top and bottom resin lens plate are welded tightly via the welding portion.
