PROBLEM TO BE SOLVED: To detect charged particles included in air supplied from an air blower while suppressing reduction in the amount of charged particles.SOLUTION: An air blower 1 includes: a body 2 that has an air inlet port 21, a flow path 23, and an outlet port 22; a fan 3 that causes air to pass through the flow path 23; a charged particle generation unit 4 that has a positive discharge electrode 42 and a negative discharge electrode 41, each for generating charged particles into the flow path 23; and a charged particle sensor 5 that has a detection electrode 51 for detecting charged particles. The air blower 1 blows air including the charged particles generated by the charged particle generation unit 4 from the outlet port 22. The charged particle generation unit 4 and charged particle sensor 5 are arranged in a direction cross to the air flowing direction so as not to arrange oppositely the detection electrode 51 of the charged particle sensor 5 and the positive discharge electrode 42 and negative discharge electrode 41 in the charged particle generation unit 4. |
