Abstract: A radiographic imaging device includes: a radiation detector including plural pixels, each including a sensor portion and a switching element; a detection unit that detects a radiation irradiation start if an electrical signal caused by charges generated in the sensor portion satisfies a specific irradiation detection condition, and/or if an electrical signal caused by charges generated in a radiation sensor portion that is different from the sensor portion satisfies a specific irradiation detection condition; and a control unit that determines whether or not noise caused by external disturbance has occurred after the detection unit has detected the radiation irradiation start, and if the noise has occurred, that stops a current operation of the radiation detector, and causes the detection unit to perform detection.
