PROBLEM TO BE SOLVED: To realize the acquition of a real time signal during the time of irradiation with a radiation a simple structure inexpensively in a radiation image detector that detects the signal corresponding to a radiation image from a radiation image recording medium on which the radiation image is recorded when radiation carrying the radiation image is projected upon the medium, can acquire a real-time signal while the radiation is projected. SOLUTION: The radiation image detector is provided with a photoconductive layer in which charges are generated when the radiation is projected, an electricity storage section which accumulates the charges generated in the photoconductive layer, and a first detector 8 which detects the accumulated charges by utilizing a first stripe electrode 51 composed of a plurality of first linear electrodes 5a and a second stripe electrode 52 composed of a plurality of second linear electrodes 5b. In the detector, a second detector 7 is connected to the second stripe electrode 52. Consequently, the detector can obtain the real-time signal while the radiation is projected by detecting the current flowing to the second stripe electrode 52 in accordance with the generation of the charges in the photoconductive layer by utilizing the second detector 7.
