<p>PROBLEM TO BE SOLVED: To a minus ion generation apparatus which is miniaturized and does not require a work for connecting an electric power cord. SOLUTION: A fan motor 12 repeats high power and low power operation based on the signal outputs of an oscillation circuit 32 by operation control of a blower 10 by a blower control circuit 8, the blower 10 blows air swingingly owing to the high power and low power operation, air flows in the inside of a case 2A along with the swinging air blow, and minus ion generated by the minus ion generation apparatus 1A can be efficiently emitted through a slit 3.</p> |
