PROBLEM TO BE SOLVED: To provide a discharge unit of an air conditioner in which complication of the shape of a support member for supporting a discharge electrode and a grounding electrode is suppressed.SOLUTION: The discharge unit 6 of an air conditioner includes: the discharge electrode 11 and the grounding electrode 12 generating plasma by being applied with a discharge voltage the support member 13 a first conductor 14 and a second conductor 15. The support member 13 is made of resin and has a first discharge electrode support part 19 to support the discharge electrode 11 and a first grounding electrode support part 21 to support the grounding electrode 12. The first conductor 14 is provided inside the first discharge electrode support part 19 and electrically connects a first body side contact provided in the air conditioner body side with the discharge electrode 11. The second conductor 15 is provided inside the first grounding electrode support part 21 and electrically connects a second body side contact provided in the air conditioner body side with the grounding electrode 12. The discharge electrode 11 and the grounding electrode 12 are exposed from the support member 13.
