A radiographic image capturing system includes: a mammography apparatus that emits radiation having a first energy to a subject and captures a first radiographic image with a radiation detector and emits radiation having a second energy greater than the first energy to the subject and captures a second radiographic image with the radiation detector and that captures the first radiographic image and the second radiographic image with a breast in a state in which a contrast medium using iodine is administered. The radiographic image capturing system includes a phantom for evaluation of the mammography apparatus that has a solid material containing at least one element, which has a value of a k absorption edge that is equal to or greater than the first energy and equal to or less than the second energy, as an image evaluation pattern simulating the contrast medium.
