<p>A particulate matter detection device (100) includes a detection device body (1) that extends in one direction and has at least one through-hole (2) that is formed at one end of the detection device body (1), a high-voltage electrode (11) and a low-voltage electrode (12) that are buried in the wall of the detection device body (1) that defines the through-hole (2), a high-voltage takeout lead terminal (11a) that is disposed on the surface of the detection device body (1), a high-voltage takeout lead terminal insulating member (20) that has a tubular shape and is disposed to cover at least an area in which the high-voltage takeout lead terminal (11a) is disposed, and a detection device outer tube (30) that is formed of a metal material and is disposed to cover the high-voltage takeout lead terminal insulating member (20), the particulate matter detection device (100) being configured so that particulate matter contained in a fluid that flows into the through-hole (2) can be electrically adsorbed on the wall surface of the through-hole (2), and the particulate matter adsorbed on the wall surface of the through-hole (2) can be detected by measuring a change in electrical properties of the wall that defines the through-hole (2).
