PLASMA GENERATION DEVICE AND CLEANING DEVICE IN WHICH PLASMA GENERATION DEVICE IS USED

摘要

A plasma generation device (1), provided with: a plasma generator (10), a plasma power supply unit (2), and a gas supply unit (3). The plasma generator includes a partition part (12) for dividing the liquid housing unit (15) and the gas housing unit (14) from each other. The partition part has a gas channel (13) for guiding the gas supplied from the gas supply unit and housed in the gas housing unit to the liquid housing unit. The first electrode (18) is disposed in the gas housing unit and the second electrode (19) is disposed in the liquid housing unit. The plasma power supply unit generates a potential supplied to the first and second electrodes and sets the potential of the second electrode to a lower value than that of the potential of the first electrode. The second electrode is formed from a material, a material compound, or a material mixture that causes sputtering phenomenon.
