A method is provided for manufacturing an electrode supporting base plate of a radiation detector wherein a plurality of high-voltage electrodes and signal detecting electrodes are alternately arranged at equal intervals and detection signals of incident radiation are obtained from the signal detecting electrodes. According to this method, a master of the base plate is processed at high precision from a material which allows easy processing and which has a small thermal expansion coefficient. A transfer mold is prepared by transferring a pattern of the master on an elastic molding material. A resin is injected in the transfer mold to manufacture an electrode supporting base plate.

Method of manufacturing electrode supporting base plate for radiation

A radiation detection element comprises an insulating base frame having a pair of leg portions with a spacing left therebetween, a pair of electroconductive members each disposed on one surface of the corresponding leg portions of the base frame, an electrode plate disposed on the rear surface of the base plate to cover the spacing between the leg portions, and a plurality of signal electrode wires spanned between the electroconductive members such that they confront the electrode plate, in which an insulating member is disposed between the base frame and the electroconductive member and/or between the base frame and the electrode plate such that its longitudinal edge portion is overhung into the spacing of the base frame.
