An uneven structure on one substrate surface for an optical element is provided with a plurality of projections. The contour shape of the projections has an arc shape in plan view facing the one surface. The contour shape is formed by a first arc section and second arc section having different center points. The first arc section and second arc section bulge in mutually opposite directions.
