  The partition plate 5 stands vertically on the ion generation surface 10 and partitions the positive ion generation part 8a and the negative ion generation part 8b. One end of the partition plate 5 abuts against a spring (elastic body) 4 provided on the concave base 3 of the housing 12, and the partition plate 5 is urged in the direction of arrow D. As the partition plate 5 moves, the other end of the partition plate 5 comes into contact with the inner wall 12 d in the air passage 17.

  Thereby, the air path 17 is partitioned by the partition plate 5 into the positive side air path 17a and the negative side air path 17b. A buffer member 6 made of resin is provided at the tip of the partition plate 5. Therefore, it is possible to prevent the inner wall 12d from being damaged by the spring 4, and to eliminate the gap between the buffer member 6 and the inner wall 12d so that the positive side air passage 17a and the negative side air passage 17b communicate with each other.

_{^{H + (H 2 O) m}} + O 2 - (H 2 O) n → · OH + 1 / 2O 2 + (m + n) H 2 O ··· (1)
_{^{H + (H 2 O) m}} + H + (H 2 O) m '+ O 2 - (H 2 O) n + O 2 - (H 2 O) n'
→ 2 · OH + O ₂ + (m + m ′ + n + n ′) H ₂ O (2)
_{^{H + (H 2 O) m}} + H + (H 2 O) m '+ O 2 - (H 2 O) n + O 2 - (H 2 O) n'
→ H ₂ O ₂ + O ₂ + (m + m ′ + n + n ′) H ₂ O (3)
