1. An ionizer comprising:
a positive-side transformer and a negative-side transformer, each of which has a primary side and a secondary side, the primary sides of the positive-side transformer and negative-side transformer being alternately connected to an alternating current power supply by a switch mechanism, and also has a ground terminal and a power supply terminal on the secondary side;
a positive-side high-voltage output circuit that has a first input terminal, a second input terminal, and a first output terminal, the first input terminal being connected to the ground terminal in the positive-side transformer, the second input terminal being connected to the power supply terminal in the positive-side transformer, a direct-current positive high voltage being output from the first output terminal;
a negative-side high-voltage output circuit that has a third input terminal, a fourth input terminal, and a second output terminal, the third input terminal being connected to the ground terminal in the negative-side transformer, the fourth input terminal being connected to the power supply terminal in the negative-side transformer, a direct-current negative high voltage being output from the second output terminal;
a discharge electrode connected to the first output terminal in the positive-side high-voltage output circuit;
a ripple-voltage attenuating capacitor that mutually connects the ground terminal in the positive-side transformer and the first input terminal in the positive-side high-voltage output circuit; and
a connection line that mutually connects the second output terminal in the negative-side high-voltage output circuit and the first input terminal in the positive-side high-voltage output circuit.
