PROBLEM TO BE SOLVED: To provide a heat dissipation structure of an adding valve capable of efficiently dissipating heat of the adding valve.SOLUTION: A heat dissipating structure of an adding valve includes: an adding valve 20 that adds a reducing agent into an exhaust duct 11 of an internal combustion engine; and a heat dissipating member 30 that dissipates heat of the adding valve 20. The heat dissipating member 30 has a housing space 32 for housing the adding valve 20, and the adding valve 20 is housed in the housing space 32. A copper powder 42 is filled between the adding valve 20 and the heat dissipating member 30, in the housing space 32 of the heat dissipating member 30. |
