摘要：
The present invention discloses a diffractive optical element whose optical axis can be precisely positioned, and a method of manufacturing the diffractive optical element. The diffractive optical element includes a region provided with a concentric uneven pattern and having a predetermined light bending characteristic, and a peripheral section worked so that the optical axis of the diffractive optical element determined by the light bending characteristic of the region aligns with the center of the profile of the diffractive optical element.
