ABSTRACT:
A diffractive optical element that can be molded readily, an imaging apparatus incorporating the diffractive optical element, and a method for manufacturing the diffractive optical element are provided. A diffractive optical element (10) includes a substrate (11) that is made of a first material containing a resin and has a surface (11a, 11b) on which a diffraction grating pattern (12a, 12b) is formed, and a coating film (13a, 13b) that is made of a second material containing a resin and is disposed so as to be in contact with a portion of the diffraction grating pattern (12a, 12b), and at least one material selected from the first material and the second material is a composite material containing inorganic particles.
