A medical X-ray image detecting device arranged such that an X-ray image sensor comprising an x-ray fluorescent element, a solid-state image pickup device and a plurality of optical fiber bundles for optically connecting the fluorescent surface of the X-ray fluorescent element to the image pickup surface of the image pickup device, is housed in an outer casing, the medical image detecting device being characterized in that it further comprises an X-ray intensity detecting element disposed in the casing adjacent to the X-ray fluorescent element. Clear X-ray images with a constant blackening degree can be obtained by controlling X-ray radiation time using the X-ray dose calculated by integrating the X-ray intensity output from the X-ray intensity detecting element with respect to X-ray exposure time.
