摘要：<p>Described is an optical part, whose set-up position, shape, and size are properly controlled. The optical part (100) comprises a substrate (10) having an optical surface (12a), a spire part (24) being set up in a manner to surround the optical surface, and an optical member (32) at least partly being placed on the optical surface (12a). A tip (24c) of the spire part (24) is located at a higher position than the optical surface (12a). <IMAGE></p>
