Abstract: In order to reduce time required for a purification catalyst to be activated in a plasma generation device for generating plasma upstream of the purification catalyst that purifies exhaust gas of an engine, the plasma is caused to effectively contact with the purification catalyst. The plasma generation device 20 includes a passage formation member 41 arranged upstream of the purification catalyst 31 in an exhaust passage 30 and formed with an internal passage 40 that the exhaust gas passes through, and a plasma generation part 29 that generates plasma in the internal passage 40. The internal passage 40 is located in the vicinity of or abutting contact with the purification catalyst 31 at an outlet part of the internal passage so that the exhaust gas flowing through the internal passage 40 causes the plasma generated by the plasma generation part 29 to blow out from an outlet 43 of the internal passage 40 and to reach the purification catalyst.
