A particulate matter detection device (100) includes a first electrode (10) that includes a conductive section (12) and a dielectric (14) that covers the conductive section (12), and a second electrode (20) that is disposed opposite to the first electrode (10) at an interval of 0.3 to 3.0 mm. Charged particulate matter contained in a fluid that passes through the space between the first electrode (10) and the second electrode (20), or particulate matter that is contained in a fluid and charged by a discharge that occurs due to application of a voltage between the first electrode (10) and the second electrode (20) is electrically adsorbed on at least one of the first electrode (10) and the second electrode (20), and the particulate matter adsorbed on the first electrode (10) and the second electrode (20) is detected by measuring a change in electrical properties of the first electrode (10), or a change in electrical properties of the first electrode (10) and the second electrode (20).
