Claim Text:
1. A gas treatment device, comprising: a gas flow path having an inside wall surface and an axial direction along which a gas flows; a multiple fixed electrodes fixed to the inside wall surface; a fan having a fan blade and a shaft that supports the fan in the gas flow path in a manner that rotates an outer circumferential surface of the fan blade along the inside wall surface; a moving electrode provided to the outer circumferential surface of the fan blade; a power supply that supplies an electric power to the fixed electrode to generate an electric discharge in a gap between the fixed electrodes and the moving electrode; and at least one antenna located at the inner wall surface of the gas flow path at a location shifted from the fixed electrodes in the axial direction and each of the antenna is exposed in the gas flow path at a midpoint of the two adjacent fixed electrodes and an electromagnetic wave oscillator that oscillates an electromagnetic wave to the antenna so as to radiate the electromagnetic wave to said gap via the antenna, wherein the shaft and fan blade of the fan comprise conductive material via which the moving electrode is grounded.
