Abstract:
A diffractive optical element is provided that includes a first resin layer having steps on one surface, a second resin layer integrated with the first resin layer in tight contact, and a high refractive index layer disposed between a wall surface of the first resin layer and a wall surface of the second resin layer, wherein the high refractive index layer has a refractive index higher than those of the first resin layer and of the second resin layer, and the high refractive index layer is formed continuously to extend beyond the boundary between the wall surface and the inclined surface adjacent thereto, and to partly overlap the inclined surface.

Claim (Index 2):
The diffractive optical element according to  claim 1 ,\n wherein, in a cross section along a thickness direction, the first resin layer has a grating ridge, and at the grating ridge, a length of a portion of the high refractive index layer overlapping the portion of the adjacent one of the inclined surfaces is 0.1 \u03bcm or more, and the first resin layer has a grating trough, and at the grating trough, a length calculated by subtracting a thickness of the high refractive index layer over the wall surfaces from a length of a portion of the high refractive index layer overlapping the portion of the adjacent one of the inclined surfaces is 0.2 \u03bcm or more.
