Patent ID: 8230721

Claim:
A particulate matter detection device, comprising: a detection device body that extends in one direction and has at least one through-hole that is formed at one end, at least one pair of electrodes that are buried in the wall of the detection device body that defines the through-hole, and are covered with a dielectric, lines that respectively extend from the pair of electrodes toward the other end of the detection device body, a takeout lead terminal of one electrode of the pair of electrodes, the takeout lead terminal of the one electrode being disposed on the surface of the other end of the detection device body, and connected to the line that extends from the one electrode, a takeout lead terminal of the other electrode of the pair of electrodes, the takeout lead terminal of the other electrode being disposed on the surface of the detection device body between the one end and the other end, and connected to the line that extends from the other electrode; and an electric wire that is provided with an electric wire securing member at its end, and bonded to the takeout lead terminal of the other electrode through the electric wire securing member, wherein the particulate matter detection device being configured so that particulate matter contained in a fluid that flows into the through-hole can be electrically adsorbed on the wall surface of the through-hole by applying a voltage of 50 to 200 kV/cm between the pair of electrodes through the takeout lead terminals using the other electrode as a high-voltage electrode, and the particulate matter adsorbed on the wall surface of the through-hole can be detected by measuring a change in electrical properties of the wall of the detection device body that defines the through-hole.
