Abstract:
A diffractive optical element  10  includes a first diffraction grating  4 , a second diffraction grating  5 , films  6  formed between the first diffraction grating  4  and the second diffraction grating  5 . The DOE  10  satisfies a conditional expression of n 2 <n 1 <n ha , where n ha  is an average refractive index of films  6 b  formed between grating wall surfaces  4 b  and grating wall surfaces  5 b  at a wavelength of 550 nm, n 1  is a refractive index of the first diffraction grating  4  at a wavelength of 550 nm, and n 2  is a refractive index of the second diffraction grating  5  at a wavelength of 550 nm. The films  6 b  and films  6 a  that are formed between grating surfaces  4 a  and grating surfaces  5 a  satisfy a predetermined relationship.

Claim (Index 9):
The diffractive optical element according to  claim 8 , wherein the following conditional expression is satisfied:\n ( n 1 +n 2 \u22122 n s ( r )) 2 <0.3, where n s (r) is a refractive index at a wavelength of 550 nm of a part of the film that is formed between the grating surface of the first diffraction grating and the grating surface of the second diffraction grating at a position a distance r away from a center of the concentric diffraction gratings.
