Summary:PROBLEM TO BE SOLVED: To produce a hologram recording film, in which a diffraction grating layer having interference fringes different in slant angle is multilayered, by a simple method. SOLUTION: The hologram recording film manufacturing method includes: a step (A) of obtaining a laminated structure 13 by alternately laminating M (where M≥2) photosensitive material precursor layers 11A, 11B and at least one (M-1) resin layer 12A on one another; a step (B) of obtaining M photosensitive material layers 21A, 22A, 21B, where at least two interference fringes with a desired pitch and a desired slant angle are formed on each of the M photosensitive material layers, from the M photosensitive material precursor layers by irradiating the laminated structure 13 with a reference laser light beam and an object laser light beam; and a step (C) of making the slant angles of the M photosensitive material layers 21A, 21B different from each other while retaining the pitch value, which is defined on a face of the photosensitive material layer, by irradiating the laminated structure 23 with an energy ray from the one face side of the laminated structure 23, and heating the laminated structure.
