Abstract (en)

[Object] To provide a plasma reactor electrode capable of effectively removing PM (particulate matter) while suppressing increase of an exhaust pressure of an exhaust gas. [SolutionMeans] A plasma reactor electrode installed in a plasma reactor P, disposed in an exhaust gas flow path H through which an exhaust gas passes, includes at least a low specific surface area region 1a in the exhaust gas flow path H and a high specific surface area region 1b, having a specific surface area higher than the specific surface area of the low specific surface area region.
