PROBLEM TO BE SOLVED: To provide a fuselage-wing connection part noise reduction device configured by a simple mechanism, appropriately reducing an aerodynamic noise generated at a wing leading edge without deteriorating aerodynamic performance of an aircraft. SOLUTION: The noise reduction device 100 including a leading edge sweep back angle which is larger than a wing 1 and a wing with width of 5-15% of a whole wing semi-span is attached to a tip end of a connection part of the wing 1 and a fuselage 2. The noise reduction device 100 is configured so that a section area of the wing after attaching the noise reduction device 100 is similar with a section area of the wing 1 to which the noise reduction device 100 is not attached.
