PROBLEM TO BE SOLVED: To provide radiographic apparatus minimizing the exposure dose to a patient in emitting X rays and capable of obtaining favorable radiographic images. SOLUTION: This radiographic apparatus is provided with an integrator 15 acquiring an output signal output from an X-ray detecting element 42 and adding accumulated exposure of the X rays emitted to the X-ray detecting element 42, and an exposure determination device 16 comparing the accumulated exposure with the predetermined set exposure; the output signal output from the X-ray detecting element 42 is branched into a first route including the integrator 15 and the exposure determination device 16 and a second route including an imaging control device 12; and the exposure determination device 16 determines the start and the stop of the X-ray irradiation based on the output signal output to the first route.
