A plasma reactor and an exhaust gas reduction device with the same are provided to raise quickly the temperature of an exhaust pipe by permitting exhaust gas to flow in parallel with a flame. A plasma reactor(100) includes an outer pipe(110), an inner pipe(120), a flow control unit(140), a fuel supply unit(150), and an air supply unit. The outer pipe has a hollow inside, and forms a part of a diesel particulate filter and a part of an exhaust pipe. The outer pipe has a joint portion coupled to the exhaust pipe. The inner pipe is formed within the outer pipe, and has an inside with an electrode support portion(123) for supporting an electrode(130) perpendicularly to the exhaust gas flow direction. The inner pipe has one side with an exhaust gas inlet portion(121) and the other side with a reaction portion(126) connected to one end of the electrode to form a flame. The flow control unit is arranged in parallel with the exhaust gas flow direction in the exhaust gas inlet portion, and has a venturi shape. The fuel supply unit supplies fuel and the air supply unit supplies air into the flow control unit.
