Abstract: There is provided an optical element, an imaging lens and an imaging device preventing from occurring ghosts and flares caused by unnecessary light reflected on a surface of the edge part or inside the same of the optical element, and reproducing a clear image quality. The optical element 100 comprises an effective optical portion 101, 103 and an edge part 102, 104 forming at the circumference of the effective optical portion 101, 103. A light shielding area SSI which changes in quality by laser irradiation is provided from a surface to the inside of the edge part or the inside of the same.
