A driving circuit for an electron multiplying device is provided which provides sufficient dynamic range and input-output linearity characteristic and reduces power loss to a greater extent. A cathode is set to a voltage substantially equal to the housing so that an electric field is not developed therebetween. A multiple stages of dynodes are arranged between the cathode and an anode, and a voltage multiplier is provided for applying bias voltages to the dynodes. The voltage multiplier includes a plurality of diodes and a plurality of capacitors. The capacitors are connected to respective ones of the dynodes individually to apply a voltage charged across each of the capacitors to the corresponding dynode. With such voltage multiplier, the dynodes are applied with voltages that increase with proximity of the subject dynode to the anode.
