FIG. 14 is a perspective view schematically illustrating a dielectric barrier plasma generator of the fourth embodiment. FIG. 15 is a cross-sectional view of the dielectric barrier plasma generator taken along the line A-A shown in FIG. 14. In FIG. 15, the gas buffer substrate is omitted. As shown in FIGS. 14 and 15, the plasma generator 70 is provided with the dielectric substrate 12, the high-voltage electrode 14, the low-voltage electrode 20, and the gas buffer substrate 26.
An auxiliary starting member 72 is disposed in the vicinity of the blowout outlet 30 and on the second surface 13b of the dielectric substrate 12.
