PROBLEM TO BE SOLVED: To retain ion balance of plus and minus ions generated from a static eliminator. SOLUTION: A power source part 1 and a power source control device 3 are connected by a connection wire 2, an output side of the power source control device 3 is connected to a high-voltage generation circuit 4 of a positive side and a high-voltage generation circuit 5 of a negative side. The high-voltage generation circuit 4 of the positive side is connected to an electrode needle 6 of a positive side and the high-voltage generation circuit 5 of the negative side is connected to an electrode needle 7 of a negative side. Ions generated from the electrode needles of the positive and negative sides are sprayed onto an object by a fan 8. The power source control device 3 judges a polarity and size of a static charged potential of the object by a signal of a detection resistance 10 connected to a grounding line 9, and controls an output voltage of the high-voltage generation circuits of positive and negative sides for retaining the ion balance of the object.
