Abstract:
1. A plasma treating apparatus comprising: a structure having a passage through which a fluid flows; a first electrode provided in a middle of said passage, crossing a first fluid passing surface, occupying only a part of said first fluid passing surface, and having no branch; a second electrode provided in the middle of said passage at an upstream side of said first electrode, crossing a second fluid passing surface, occupying only a part of said second fluid passing surface and having no branch, said first electrode and said second electrode crossing each other as seen in an axial direction of said passage; a third electrode provided in the middle of said passage at a downstream side of said first electrode, crossing a third fluid passing surface, occupying only a part of said third fluid passing surface and having no branch, said first electrode and said third electrode crossing each other as seen in the axial direction of said passage; a pulsed power supply for generating a pulse voltage between a first pole and a second pole; and a connecting line for electrically connecting said first electrode to said first pole and electrically connecting said second electrode and said third electrode to said second pole, wherein said first electrode and said second electrode are opposed apart in an axial direction of said passage and said first electrode and said third electrode are opposed apart in the axial direction of said passage.
