An X-ray detector with a multi-channel type ionization chamber has plural signal plate electrodes and plural high voltage plate electrodes respectively disposed in parallel to and alternating with the signal plate electrodes all of the plate electrodes being mounted between a pair of insulators. A conductive rubber member is provided between one of the insulators and the high voltage plate electrodes, and a long conductive member is provided along the conductive rubber member at a position where the long conductive member contacts the rubber member, but does not contact the high voltage plate electrodes. Thereby, the amount of X-rays is detected accurately in respective channels in spite of the simple construction of the X-ray detector.
