摘要： A second region (12) composed of a plane is formed around a first region (11) having a lens function, and a third region (13) is formed between the first region and the second region. A protection film (24) is formed on the surface of the first region 1. The first region is protruded relative to the second region, the third region is formed throughout the rim of the first region 1, and the surface of the third region is recessed relative to a virtual curved surface (11a) that is a curved surface along the surface shape of the first region being extended to the second region. Consequently, it is possible to form throughout the first region a protection film having a surface shape that substantially matches the surface shape of the first region.

摘要： In a diffraction optical element having a structure in which a base and an optical adjustment layer adhere to each other, defects such as cracks and peeling occur in the optical adjustment layer, when the adhesive strength between the base and the optical adjustment layer is degraded. In a diffraction optical element 100 of the present invention, a plurality of anchor grooves 3 are formed in a planar second region 6 of a base 1. Further, a depth of an anchor groove of the plurality of anchor grooves 3, which is positioned on an outermost side, is designed so as to be smaller than a depth of another anchor groove of the plurality of anchor grooves 3, which is positioned on an innermost side. An optical adjustment layer 9 adheres so as to cover a first region 5 in which a diffraction grating 2 is formed and the second region 6 in which the anchor grooves 3 are formed of the base 1.
