摘要：

An optical lens 11, which has a lens section with a refractive power, has concave marks 33, 35, 37, and 39 which are formed to be recessed on a surface of the lens section, in an effective optical lens surface which contributes to image forming of the lens section. A width of each of these concave marks 33, 35, 37, and 39 is equal to or greater than 0.05 μm and equal to or less than 14 μm, and a depth of recession of each concave mark is equal to or greater than 0.05 μm and equal to or less than 5 μm.
