There are provided a phantom capable of reducing the time required to acquire calibration data even if a radiation field is large, a radiographic imaging device, and a method for calibrating a photon counting detector. A phantom, which is used in acquisition of calibration data for a photon counting detector that outputs an electric signal based on photon energy of incident radiation, includes a first basis material and a second basis material that are known materials. The first basis material has a smaller attenuation coefficient for the radiation than that of the second basis material. The first basis material varies in thickness in a stepwise fashion in a direction perpendicular to a radiation field of the radiation and, in each step, the step decreases in thickness with distance from a center of the radiation field in a direction of arrangement of detection elements of the photon counting detector.
