| abstract | PROBLEM TO BE SOLVED: To provide an optical element capable of effectively preventing image deterioration due to diffracted light, and an optical system and electronic equipment using the same. SOLUTION: There are a plurality of grooves that include at least one reflection surface 12, 22, 23, and are arranged in contact with each other at substantially equal intervals on the surface of the reflection surface, and a protrusion between a cross section of the groove or adjacent grooves. The optical elements 10 and 20 satisfying the following conditional expression in which the cross section of the part is a substantially circular arc. 0.03 ≦ (n 0 × P 2 ) / (R × λ 0 ) ≦ 0.17 (1) Where λ 0 is the reference wavelength within the wavelength range to be used, n 0 is the refractive index at the reference wavelength of the material constituting the optical element, and R is the radius of curvature of the arc cross section of the protrusion between the groove cross section or adjacent grooves. , P: spacing between adjacent grooves.
