Abstract
A particulate matter sensor which may be used as an onboard particulate matter diagnostic sensor includes an insulating base that has at least a pair of opposing plane surfaces, an electrode nucleus that is formed on one of the pair of opposing plane surfaces of the base, and forms an electrode when a conductive substance adheres to the plane surface, and an electrode that is disposed parallel to the electrode nucleus and is provided on the other of the pair of opposing plane surfaces, or provided on a side surface of the base that is adjacent to the pair of opposing plane surfaces, or provided inside the base.
