Abstract
An ionization chamber comprises a plurality of cylindrical electrodes which are coaxially arranged, and a casing which holds the cylindrical electrodes in it under the condition allowing the axial shifting of the edges of the cylindrical electrodes but preventing the radial shifting of the cylindrical electrodes whereby the slight relative deviation of parts for the ionization chamber can be minimized during use at high temperature or during a severe thermal cycle.
