Abstract
A device for securing an optical element in which, when an opposing surface of a mold for forming a base is formed so that a mounting surface of the base is formed at an angle equal to 90 degrees plus a very small angle, the mounting surface is smoothly formed when the mold is removed from the base. Therefore, it becomes unnecessary to mechanically cut the mounting surface, so that it can serve as a reference surface for directly securing the optical element thereto. This makes it possible to simplify the manufacturing process of the base and to reduce costs.
