PROBLEM TO BE SOLVED: To provide a resonator capable of reducing the noise in a wide frequency range. SOLUTION: The resonator 1 comprises a body case 2, a resonance pipe 3 and a partitioning member 4, and the partitioning member 4 has a communication hole 41 to communicate a plurality of resonance chambers 5a and 5b partitioned by the partitioning member 4. The resonator can reduce the noise in a wide frequency range. COPYRIGHT: (C)2005,JPO&NCIPI
