Provided is an electrostatic precipitator that, when collecting particulate matter (PM), does not require a large-volume air purging unit, tends not to clog, exhibits minimal re-entrainment even in high-speed air flows, demonstrates excellent collection performance, and tends not to fail. The present invention is provided with: a plate electrode (20) in which are formed a plurality of holes through which PM passes; a discharging electrode (30) disposed so as to face one surface of the plate electrode; a discharge generation unit for applying a voltage between the plate electrode and the discharging electrode to generate a discharge for providing a Coulomb force to the particulate matter; a PM-collecting collection region formed on the side opposite the side on which the discharge electrode faces the plate electrode; a gas circulation region (33) in which a PM-containing gas is caused to circulate, the gas circulation region (33) formed between the plate electrode and the discharging electrode; and a PM recovery unit (50) that separatingly recovers PM collected by circulating a recovery gas in a direction intersecting the PM-gas circulation direction in the collection region. |
