Abstract: A particulate matter sensor unit according to an embodiment of the present invention comprises: an exhaust line through which exhaust gas passes; and an electrostatic induction type sensor which is installed on one side of the exhaust line and generates charged particles when charged particulate matter included in the exhaust gas pass nearby. An electrode unit is formed on the entire surface of the sensor close to the particulate matter. The electrode unit can be a furrow type which protrudes in a direction crossing the direction in which the exhaust gas flows.
