There is provided a radiographic imaging device including: a radiation source that irradiates radiation generated by inverse Compton scattering； a first grating at which first members that diffract or absorb radiation are formed side by side such that pitches thereof are larger where distances from a center position of the radiation irradiated from the radiation source are larger, the first grating diffracting or absorbing radiation irradiated from the radiation source with the first members； a second grating that is disposed at a position at which Talbot interference is produced by the radiation diffracted or absorbed by the first grating, and at which second members that absorb radiation are formed side by side such that pitches thereof are larger where distances from the center position of the radiation irradiated from the radiation source are larger； and a radiation detector that detects radiation that has passed through the second grating.
