PROBLEM TO BE SOLVED : To provide an electrostatic dust collector which increases the collection efficiency by effectively sending a fine particulate material into the pocket area of electric field zero utilizing ionic air and which prevents the re-scattering by controlling the stripping due to the induction charge of the collected particulate material. SOLUTION : In the electrostatic dust collector in which the gas stream passage to feed a gas containing the particulate material between a discharge electrode and dust collecting electrode that are oppositely arranged is formed and in which high voltage is applied to both electrodes to electrify the particulate material in the gas flowing through the gas stream passage so that it can be collected in the dust collecting electrode, a required number of dust collecting pockets where the space electric field strength in the inner atmosphere to store the particulate material is zero are installed at the opposite face of the dust collecting electrode against the discharge electrode with intervals in the flowing direction of the gas flowing through the gas stream passage.
