Zusammenfassung:	PURPOSE:To provide a charge neutralizer for particle beam which efficiently neutralize the charge of such particle beam as large current ion beam. CONSTITUTION:For the charge neutralizer for particle beam which neutralizes positive charge of high speed particle beam with electrons from an electron source, an electron gun 1 is used as an electron supply source, an electrode 2 for moderating and reflecting the electrons emitted from the electron gun 1 is provided to constitute so that the high speed particle beam passes in the moderated and reflected electron cloud, and an electric potential determination electrode 5 for leading the electron to near the central axis of the particle beam passing path is provided to constitute so as to be able to control the space density of electrons.
