PROBLEM TO BE SOLVED: To solve a problem that when two pieces of booster coils are connected to one minus ion electrode and one plus ion electrode respectively and independently, both primary coils must be connected in series in order to arrange that the same amount of current flows in each primary coil of both booster transformers, however, since inductance and direct current resistance divider differ and the voltage amounts divided do not coincide with each other depending on the environment or the like where each booster transformer is installed, there is a difference between an amount of the plus ions generated and that of the minus ions generated. SOLUTION: Two pieces of booster transformers consisting of one piece of primary coil and one piece of secondary coil are installed so that respective secondary coils are connected to respective discharge electrodes, and each primary coil is connected in parallel, a capacitor to supply power to the primary coil is connected to each primary coil respectively and individually, and furthermore, it is arranged that AC current is supplied to each capacitor from one common power source supply portion.
