A radiographic imaging apparatus including: a scintillator that includes at least a columnar crystal and converts irradiated radiation into light a light receiving element that receives light emitted from the scintillator and a sensor substrate that comprises a light receiving element that receives light emitted from the scintillator and converts the received light into an electric signal, a cross-sectional diameter of the columnar crystal in a region located at a sensor substrate side being larger than that in a region located at a side opposite to the sensor substrate side.
