An exhaust gas purification apparatus can efficiently purify an exhaust gas even when hydrocarbon contained in the exhaust gas is excessive with content of hydrocarbon and NOx being substantially different. The apparatus has an oxidation catalyst unit ( 8 ), a plasma processing unit ( 4 ) and a NOx purification catalyst unit ( 5 ) arranged on an exhaust gas flow passage, through which the exhaust gas discharged from an engine ( 1 ) flows, in this order form an upstream side to a downstream side. The oxidation catalyst unit ( 8 ) is provided with a main flow passage ( 31 ) through which the exhaust gas flows while being in contact with an oxidation catalyst, and a bypass flow passage ( 9 ) through which the exhaust gas flows without contacting the oxidation catalyst.
