A radiographic image processing device includes: an image acquisition section that acquires a subject image detected by a shielded detection portion and a non-shielded detection portion; an area information acquisition section that acquires area information which is information for specifying a non-shielded image area and a shielded image area; and a scattered ray suppression section that estimates spreading of scattered rays generated in a non-shielded subject portion, estimates that scattered rays that spread to the non-shielded image area from a shielded subject portion are not present, calculates a scattered ray component in each position in the non-shielded image area as the estimated scattered rays reach each position in the non-shielded image area, and suppresses the scattered ray component in each position in the non-shielded image area according to the calculated scattered ray component.
