PROBLEM TO BE SOLVED: To provide an intake sound introduction device capable of regenerating powerful intake sound including a half-order component.SOLUTION: An induction pipe 160 of an intake sound introduction device 100 has: a first communication pipe 120 branched from a first intake passage 35 of an internal combustion engine 20, and connected to a resonance box 110; and a second communication pipe 130 branched from a second intake passage 45 and connected to the first communication pipe 120. The first pipe length that is length of the first communication pipe 120 between a branch portion 36 of the first communication pipe 120 branched from the first intake passage 35, and a connection portion 135 of the first communication pipe 120 connected to the second communication pipe 130 is different from the second length of the second communication pipe 130 between a branch portion 46 of the second communication pipe 130 branched from the second intake suction passage 45 and a connection portion 135 of the second communication pipe 130 connected to the first communication pipe 120.SELECTED DRAWING: Figure 1 【課題】ハーフ次数成分を含んだ迫力のある吸気音を発生させることのできる吸気音導入装置を提供する。【解決手段】吸気音導入装置１００の導入管１６０は、内燃機関２０の第１吸気通路３５から分岐して共鳴箱１１０に接続される第１連通管１２０と、第２吸気通路４５から分岐して第１連通管１２０に接続される第２連通管１３０とを有している。第１連通管１２０において第１吸気通路３５から分岐した分岐箇所３６と第１連通管１２０において第２連通管１３０が接続された接続箇所１３５との間の第１連通管１２０の管長である第１管長と、第２連通管１３０において第２吸気通路４５から分岐した分岐箇所４６と第２連通管１３０において第１連通管１２０に接続された接続箇所１３５との間の第２連通管１３０の管長である第２管長とが異なっている。【選択図】図１
