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 1):
A diffractive optical element comprising:\n a first resin layer having a first surface, the first surface having a plurality of steps, wherein the plurality of steps include a plurality of wall surfaces and a plurality of inclined surfaces each bounded by the wall surfaces; a second resin layer disposed on a side closer to the first surface of the first resin layer, wherein a surface, of the second resin layer, on a side closer to the first resin layer has a plurality of steps respectively corresponding to the steps of the first resin layer; and a high refractive index layer disposed between the wall surfaces of the first resin layer and a corresponding one of the wall surfaces of the second resin layer, wherein the high refractive index layer has a refractive index higher than refractive indices of the first resin layer and of the second resin layer, wherein the high refractive index layer is formed to extend beyond the wall surfaces, and to overlap portions of adjacent ones of the inclined surfaces.
