An optical element 100 has a shape as a rectangular parallelopiped or approximately rectangular parallelopiped formed on one surface 100U with a convex portion 103D. The optical element 100 has a substrate (base) 101 and a lens 102. The substrate 101 and the lens 102 of the optical element 100 have refractive indexes different from each other. The substrate 101 has an approximately axially symmetric concave portion 101B in a bottom surface 100B. The concave portion 101B is filled with an optical material having a refractive index different from the substrate 101, while the lens 102 is formed by the concave portion 101B filled with the optical material. A flat portion 103E is formed around the convex portion 103D. Axes of symmetry of the convex portion 103D and the concave portion 101B of the substrate 101 are positioned on an identical straight line or approximately identical straight line and are approximately vertical with respect to the flat portions 103E and 101C. |
