摘要
A diffractive optical device 1 is composed of resins of different materials, and has a laminated structure, in which a second diffractive device element 20 is bonded between a first diffractive device element 10 and a third diffractive device element 30; a first diffraction optical surface 6 is formed by adhering a diffraction grating groove 2, which is formed on the first diffractive device element 10, to a diffraction grating groove 3, which is formed on the second diffractive device element 20, on a bonding surface of the first diffractive device element 10 and the second diffractive device element 20, a second diffractive optical surface 7 is formed by adhering a diffraction grating groove 4, which is formed on the second diffractive device element 20, and a diffraction grating groove 5, which is formed on the third diffractive device element 30, on a bonding surface of the second diffractive device element 20 and the third diffractive device element 30, and both the non-bonded surface of the first diffractive device element 10 and the non-bonded surface of the third diffractive device element 30 are composed of planes.
