PROBLEM TO BE SOLVED: To supply ionized air to each of a plurality of branch flow passages which are branched out from a main flow passage. SOLUTION: An ion generator is provided with a discharge needle and a conductor serving as discharge electrodes individually ionizes air flowing inwardly from an air inflow port, to let it flow outward from an air outflow port. The air outflow port is connected to a branch joint 24, in which the main flow passage 28 and a plurality of branch flow passages 32a, 32b are formed, and they are connected mutually in a crossing part 34. In the crossing part 34, a partition wall 35 protruded toward the main flow passage 28 is arranged, and ionized air inside the main flow passage 28 is fed into the branch flow passages 32a, 32b, after it is previously divided by means of the partition wall 35.
