An electrostatic precipitator, comprising: a housing; a plate-shaped electrode having formed therein a plurality of through holes that allow a particulate matter to pass therethrough, wherein the plate-shaped electrode is arranged in the housing such that the plate surface thereof is in a vertical direction; a discharge electrode disposed to face, from a predetermined distance, one surface of the plate-shaped electrode; a discharge generating unit (45, 130) that is configured to apply a voltage between the plate-shaped electrode and the discharge electrode and to generate an electric discharge imparting a Coulomb force to the particulate matter; a collection region that is formed on an opposite side of the plate-shaped electrode to a surface thereof facing the discharge electrode and that is configured to collect the particulate matter; a gas flow-through region that is formed between the plate-shaped electrode and the discharge electrode and allows gas including the particulate matter to flow therethrough; an exhaust gas introducing port, formed in a lower part of the housing, and an exhaust gas discharge port, formed in an upper part of the housing, being arranged such that the gas including the particulate matter introduced into the housing from the exhaust gas introducing port flows through vertically and is discharged from the exhaust gas discharge port; and a particulate matter recovery unit (50, 51, 60, 64) that is configured to cause a recovery gas to flow through in the collection region in a direction crossing the flow-through direction of the gas including the particulate matter, wherein the electrostatic precipitator is configured such that, when the particulate matter in the gas including particulate matter is electrically charged by the electric discharge, the electrically charged particulate matter in the gas including particulate matter is collected in the collection region through the through holes, and the particulate matter collected in the collection region is stripped away and recovered by the recovery gas while not being re-entrained. a housing; a plate-shaped electrode having formed therein a plurality of through holes that allow a particulate matter to pass therethrough, wherein the plate-shaped electrode is arranged in the housing such that the plate surface thereof is in a vertical direction; a discharge electrode disposed to face, from a predetermined distance, one surface of the plate-shaped electrode; a discharge generating unit (45, 130) that is configured to apply a voltage between the plate-shaped electrode and the discharge electrode and to generate an electric discharge imparting a Coulomb force to the particulate matter; a collection region that is formed on an opposite side of the plate-shaped electrode to a surface thereof facing the discharge electrode and that is configured to collect the particulate matter; a gas flow-through region that is formed between the plate-shaped electrode and the discharge electrode and allows gas including the particulate matter to flow therethrough; an exhaust gas introducing port, formed in a lower part of the housing, and an exhaust gas discharge port, formed in an upper part of the housing, being arranged such that the gas including the particulate matter introduced into the housing from the exhaust gas introducing port flows through vertically and is discharged from the exhaust gas discharge port; and a particulate matter recovery unit (50, 51, 60, 64) that is configured to cause a recovery gas to flow through in the collection region in a direction crossing the flow-through direction of the gas including the particulate matter, wherein the electrostatic precipitator is configured such that, when the particulate matter in the gas including particulate matter is electrically charged by the electric discharge, the electrically charged particulate matter in the gas including particulate matter is collected in the collection region through the through holes, and the particulate matter collected in the collection region is stripped away and recovered by the recovery gas while not being re-entrained.
