To improve the quality of a radiographed image.

This radiographic device comprises an X-ray tube 11 having a negative electrode 12 for generating electron beams and a positive electrode 13 having a target surface 13a for emitting X-ray to a prescribed range including a prescribed directional emitting axis by collision of the electron beams, and a grid 16 formed of an alternate arrangement of a shielding material 16a for shielding X-ray and a transmitting material 16b transmitting X-ray and arranged between the X-ray tube 11 and a subject 17. The arrangement direction of the shielding material 16a to the radiative axis is uniformized.
